Use Bazel CI sharding on tasks that benefit from it.

This cuts down our presubmit times to ~29min. Further improvements will follow from migrating all Linux tasks to use RBE and tweaking the shard counts and sharding algorithm.

Test run (with a bogus change to a Java file in order to not get cache hits for integration tests): https://buildkite.com/bazel/google-bazel-presubmit/builds/24778

This was a collaborative effort by fwe@, who implemented the sharding feature for our Bazel CI and did initial tests: https://github.com/bazelbuild/continuous-integration/pull/618 and myself, fixing the remaining blockers (https://github.com/bazelbuild/continuous-integration/commit/2a160432657bb1335f8fb8272832a208c2224d39).
