Major operations:
* Fix the go_package entries to be consistent, as the new tool
complains when it doesn't have a '/'.
* Regenerate with the new protoc-gen-go tool.
* github.com/golang/protobuf -> google.golang.org/protobuf
* proto.[Un]MarshalText -> prototext.[Un]Marshal

Soong_ui produces a build_error raw file to $(OUT_DIR) where
the file contains a list of build action errors. Each build action
error represents an error raised by a command. The build_error file
is populated if there was a build error.
Bug: b/132969697
Test: Ran m for successful build. Introduced a broken build change,
ran m and verified using printproto that build_error was
generated successfully.
