Add soong_javac_filter tool

The soong_javac_filter tool will take the output of the javac tool
on stdin and produce a colorized version similar to what clang
produces on stdout.  It also strips the useless "warning there are
warnings" messages:
   Note: Some input files use or override a deprecated API.
   Note: Recompile with -Xlint:deprecation for details.
   Note: Some input files use unchecked or unsafe operations.
   Note: Recompile with -Xlint:unchecked for details.
Modules that want the warnings can pass the appropriate -Xlint
options.

Test: javac_filter_test
