Async {AbstractFileWrite,TemplateExpansion}Action
While the contents of these files have to be evaluated locally, we have
code to write the files to remote storage, which can block the current
thread for at least one network round-trip time. These blocks show up in
the profiler, even though they don't consume any local CPU, making it
more difficult to interpret the results.
This change may improve build performance in cases where Bazel has to
write a lot of such files and also has different actions which could
execute in parallel. However, I did not measure any improvements in the
builds I tested.
Progress on #6394.
