Enable using BuildBuddy for Remote Build Execution (RBE), remote caching, and Build Event Service (BES) streaming in CI. Add `buildbuddy.bazelrc` (imported by `.bazelrc`) with a shared `_buildbuddy_base` config and two public variants: * `buildbuddy_presubmit`: isolates cache writes to the `presubmit` instance and disables local result uploads for untrusted PR runs. * `buildbuddy_postsubmit`: enables local result uploads to populate the default cache on trusted postsubmit runs.

…ta (#4313) Optimize remote execution, remote caching, and diagnostic telemetry for BuildBuddy invocations across local and CI runs. Invocation analysis (0a836a44-4d93-4312-b6d1-1e2fffd7a4ff) highlighted opportunities to enhance CAS throughput with compression and chunking, prevent build failures from CAS eviction through lost-input rewinding, and collect rich diagnostic and profiling traces for the BuildBuddy UI. Additionally, GitHub Actions runs previously lacked build metadata to correlate invocations with workflows and PRs, and developers needed an automated, secret-safe method to link workspace credentials. To address this, enable remote cache compression, experimental chunking, lost-input rewinding, diagnostic logging (bazel-remote-grpc.log and bazel-execution-log.binpb.zst), and detailed execution profiling in _buildbuddy_base. In setup-bazel, inject non-secret CI build metadata (ROLE, VISIBILITY, commit SHA, PR number, branch name, run ID, actor, and GHA workflow run links) unconditionally on build. Replace the legacy shell script with a standalone Python client setup script to configure Git triangle tracking and symlink user.bazelrc cleanly. Work towards #4289, #4300, #4304.
