chore: Add size attribute to all bazel test targets

[LKreutzer]

Signed-off-by: Lars Kreutzer lars.kreutzer@tngtech.com

Summary

• Add "size" attribute to every bazel test target.
• This sets the correct timeouts for all unit tests - see bazel docs.
• If a test took >~10s I used the "medium" label in order to avoid a one minute timeout on slow machines.

Test Plan

• Check that all tests have the attribute:

bazel query 'attr(size, small , tests(//...))' > tests-with-size.txt && \
bazel query 'attr(size, medium , tests(//...))' >> tests-with-size.txt && \ 
bazel query 'attr(size, large , tests(//...))' >> tests-with-size.txt && \
bazel query 'kind(".*_test", attr("name",".*","//..."))' > anytest.txt && \ 
diff tests-with-size.txt anytest.txt

• Run all unit tests bazel test //...
• CI

Additional Information

• This change is backwards-breaking
