Add `collect_validations_metadata` boolean flag to generated_file() targets.

The default is false, unless the .gn flag
experimental_collect_validations_metadata is set to true.

When this flag is true, metadata walks will visit validation
dependencies. This may result in runtime crashes due to the
data race described in the associated bug.

A future CL will ensure that walks that include validations
are always performed after all targets have been resolved
to fix the issue.
