feat!: use jdtls compiler (#153)

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

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