api/build: automatically generate BUILD files. (envoyproxy#8506)

This provides canonical BUILD formatting and puts protoxform in charge of being able to determine import paths, without having to worry about Bazel implications. Part of envoyproxy#8082. Risk level: Low Testing: tools/proto_sync.py, visual inspection of diffs. Signed-off-by: Harvey Tuch <[email protected]>
