[Java.Interop.BootstrapTasks] Filter out invalid JDKs

[jonpryor]

@jonpryor's developer machines are a "weird", with a macOS arm64 box containing the directories:

• $HOME/android-toolchain/jdk-17
• $HOME/android-toolchain/jdk-17.x64

Meanwhile, XAPrepareJdkLocations.GetXAPrepareJdks() within dotnet/android-tools looks for all directories matching the glob $HOME/android-toolchains/jdk*, and thus finds both.

For some reason, the JDK that dotnet build -t:Prepare *.sln winds up using by default is the the jdk-17.x64 directory (😱), which cannot be loaded into an arm64 process. This results in errors from dotnet build:

EXEC : error JM4003: jnimarshalmethod-gen: Unable to create Java VM […/dotnet/java-interop/samples/Hello-NativeAOTFromJNI/Hello-NativeAOTFromJNI.csproj]

Instead of doing the "obvious" of removing jdk.x64 or renaming it so it doesn't match the glob jdk*, update
JdkInfo.GetKnownSystemJdkInfos() and JdkInfo.GetSupportedJdkInfos() to filter out JDKs that cannot be loaded into the current process. This nicely filters out jdk-17.x64, allowing dotnet/java-interop to build successfully.
