Simplify proto rules in GN

Stop having duplicate rules for proto_library() vs protozero_library().
Turns out most of the codebase has both and we keep copy/pasting the
same boilerplate over and over.
Introduce a GN template, perfetto_proto_library(), to rule them all.
It takes care of generating both targets (zero,lite) at once and
avoids having to remember the usual generate_python = false and
proto root paths.
This is a refactoring with no intended side effects.
