[compdb] Optionally filter the compilation database.

After this patch, user can use gn gen $OUT --export-compile-command=\
"target1,target2" to optional filter the generated compdb json. With
this option, GN will only generate the targets that are reachable from
targets in this option. If this option is empty, GN will not perform
the filtering.
