feat!: use jdtls compiler

[rcasia]

Relates to #75

This is maybe what should have been done in the first place.

Reasons to use jdtls compiler are:

• it is faster
• it is more reliable
• allows neotest-java to have less responsabilities

TODO:

• Remove old code
• Add dependency to documentation and luarock
• Handle when compilation fails (already handled by nvim-jdtls)
• Also support debugger
• Check dependencies are present
• Use java_home from jdtls settings
• ability to run tests from the summary window

Noticed that when running tests that contain reflection (as this one here) throw this errors with this message:

Request processing failed: java.lang.IllegalArgumentException: Name for argument
 of type [int] not specified, and parameter name information not available via reflection. 
Ensure that the compiler uses the '-parameters' flag.

It is solved when adding org.eclipse.jdt.core.compiler.codegen.methodParameters=generate to ./your-project/.settings/org.eclipse.jdt.core.prefs
