protolog: improve build time of frameworks/base/services

Improves build time by speeding up the protolog source transformation
tool:
- parallelize the transformation to use all available cores
- remove dependency on lexicographically preserving printer
- disable comment attribution and language level validation

Speeds up the build step from ~30s to ~4s.

Test: atest protologtool-tests
Test: make services.core.protologsrc && edit file in fw/base/services/core && time make services.core.protologsrc
