RFR: 8057543: Replace javac's Filter with Predicate (and lambdas)

[Guoxiong Li]

Hi all,

This patch replaces javac's `Filter` with `Predicate` and set `Filter` as `Deprecated`.
Two existing tests failed and I fixed it.
Currently, all the tests in `test/langtools` passed locally by using the following command.

make test CONF=linux-x86_64-server-release JOBS=4 TEST=test/langtools/

Thank you for taking the time to review.

Best Regards.
