[build] Remove cmake Java support (#8952)

This is increasingly difficult to maintain, and has very limited
benefit. Modern coprocessors with enough horsepower to run Java
applications can use the Gradle or Bazel build systems instead.

 # WPILib CMake Support
 
-WPILib is normally built with Gradle, however for some systems, such as Linux based coprocessors, Gradle doesn't work correctly, especially if cscore is needed, which requires OpenCV. Furthermore, the CMake build can be used for C++ development because it provides better build caching compared to Gradle. We provide the CMake build for these cases. Although macOS is supported, these docs will only go over Linux and Windows builds, but should mostly work for macOS as well. If you are stuck, you can look at the GitHub workflows for any OS to see how it works.

 ## Prerequisites
 
 OpenCV needs to be findable by CMake. On systems like the Jetson, this is installed by default. Otherwise, you will need to build OpenCV from source and install it.
 
-If you want JNI and Java, you will need a JDK of at least version 25 installed. In addition, you need a `JAVA_HOME` environment variable set properly and set to the JDK directory.

 ## Presets
 
-The WPILib CMake setup has a variety of presets for common configurations and options used. The default sets the generator to Ninja and build directory to `build-cmake`. The other presets are `with-java` (sets `WITH_JAVA=ON`), `sccache` (sets the C/C++ compiler launcher to sccache), and `with-java-sccache` (a combination of `with-java` and `sccache`).

 On Windows, make sure the directories for the libraries you built are on PATH. For wpilib, the default install location is `C:\Program Files (x86)\allwpilib`. If you built other libraries like OpenCV from source, install them, and add the install directories to PATH. This ensures CMake can locate the libraries.
 
-You will also want to add the directories where the DLLs are located (usually the `bin` subdirectory of the install directory) to PATH so they can be loaded by your program. If you are using OpenCV and Java, the `opencv_java` DLL is located in either the `lib` subdirectory if you built but didn't install OpenCV, or the `java` subdirectory if you did install OpenCV.

-## Using the installed libraries for Java
-
-Using the built JARs is more involved than using the C++ libraries, but the additional work involves providing the paths to various libraries and JARs when needed.
-
-Create a new folder to contain your project. Add the following code below to a `CMakeLists.txt` file in that directory.
-
-```cmake
-cmake_minimum_required(VERSION 3.11)
-project(robot)

-find_package(Java REQUIRED COMPONENTS Development)
-include(UseJava)
-find_package(wpilib REQUIRED)
-find_jar(opencvJar opencv-xxx PATHS ENV PATH) # Change to OpenCV version
-
-file(GLOB_RECURSE JAVA_SOURCES *.java)
-# If you want Gradle compatibility or you are using one of the templates/examples, comment out the above line and uncomment this line instead:

-export_jars(TARGETS robot FILE robot.jar)
-```
-This includes all the built JARs except for the vendordeps. If you are not using a JAR/library, you may remove it.
-Add a `Main.java` file to contain your code, and create a build folder. Move into the build folder, and run
-
-```
-cmake /path/to/folder/containing/CMakeLists
-```
-
-After that, run `cmake --build .` to create your JAR file. To execute the JAR file, you need to include the wpilib JARs and your JAR in the classpath, and execute your Java program's entry point. If you are using cscore or cameraserver, you also need to include the path to the OpenCV JAR. If you built it from source, it will be in your OpenCV build directory. If it's installed on the system, CMake may find it from PATH, but you will likely need to locate the JAR and manually give CMake the JAR directory. If you are on Linux, you will also need to add the path of the libraries to `LD_LIBRARY_PATH`. This can be done by prepending `LD_LIBRARY_PATH=/path/to/libraries` to the Java command. If you need to add more paths, separate them with colons. The final command should look like `java -cp "robot.jar:/path/to/library_jars/*" main.package.Main`, using a semicolon to separate paths instead of a colon if you are on Windows. If you are on Linux, the final command should look more like `LD_LIBRARY_PATH=/path/to/libraries java -cp robot.jar:/path/to/library_jars/* main.package.Main`.
-
 ## Using vendordeps
 
-Vendordeps are not included as part of the `wpilib` CMake package. However, if you want to use a vendordep, you need to use `find_package(VENDORDEP)`, where `VENDORDEP` is the name of the vendordep (case-sensitive), like `xrpVendordep` or `romiVendordep`. Note that commandsv2, while a vendordep in normal robot projects, is not built as a vendordep in CMake, and is instead included as part of the `wpilib` CMake package. After you used `find_package`, you can reference the vendordep library like normal, either by using `target_link_libraries` for C++ or `add_jar` for Java.

 If you get that, you need make sure OpenCV was installed, and then reattempt to configure. If that doesn't work, set the `OpenCV_DIR` variable to the directory where you built OpenCV.
-
-#### Missing Java
-
-If you are missing Java, you will get a message like the following.
-```
-CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
-  Could NOT find Java (missing: Java_JAVA_EXECUTABLE Java_JAR_EXECUTABLE
-  Java_JAVAC_EXECUTABLE Java_JAVAH_EXECUTABLE Java_JAVADOC_EXECUTABLE

-
-If this happens, make sure you have a JDK of at least version 25 installed, and that your JAVA_HOME variable is set properly to point to the JDK.
-
-In addition, if you do not need Java, you can disable it with `-DWITH_JAVA=OFF`.
-
-#### Java: Can't find dependent libraries
-
-If one of the libraries can't be found, you will get an error similar to this one:
-
-```
-java.io.IOException: wpiHaljni could not be loaded from path or an embedded resource.
-        attempted to load for platform windows-x86_64
-Last Load Error:
-C:\Program Files (x86)\allwpilib\bin\wpiHaljni.dll: Can't find dependent libraries
-```
-
-If you get this error, that's usually an indication that not all your libraries are in your PATH. If the error is coming from cscore specifically, it's likely you're missing OpenCV. Otherwise, it's likely the wpilib libraries are not in a directory on PATH.
-
-Note that Linux will not have this specific type of error, as it will usually tell you the dependent library you are missing. In that case, you most likely need to add the library to `LD_LIBRARY_PATH`.
