Decouple non-Mac builds from Xcode dependency (#6316)

* Decouple non-Mac builds from Xcode via BAZEL_NO_APPLE_CPP_TOOLCHAIN

Set BAZEL_NO_APPLE_CPP_TOOLCHAIN=1 in .bazelrc so apple_support skips
Xcode detection (xcode-locator) entirely for Scala/C++/Go builds.
Only mactools builds (Mac/Sparkle) re-enable the Apple CC toolchain.

This means Xcode version changes no longer affect Eagle, Shardok, test,
auth, docker, or Unity Windows builds — no expunge, no cache invalidation,
no rebuild. The sync script and its expunge/cache-key logic are now scoped
to mactools only and removed from all non-Mac CI workflows.

* Revert BAZEL_NO_APPLE_CPP_TOOLCHAIN; keep Apple CC with stable environ

BAZEL_NO_APPLE_CPP_TOOLCHAIN=1 broke builds because apple_support
registers platforms (e.g. macos_x86_64) that require Apple CC toolchains
for resolution — even in non-Mac builds.

Instead, keep Apple CC enabled but ensure its repo rule never
re-evaluates on non-Mac builds by keeping DEVELOPER_DIR pinned in
common:macos. The sync script only runs for mactools builds and
overrides DEVELOPER_DIR there.

# Keeps Bazel in sync with the installed Xcode version. Two mechanisms:
# Keeps Bazel mactools builds in sync with the installed Xcode version.

# 1. Writes .bazelrc.xcode with --action_env=XCODE_BUILD_VERSION=<version>
# so the version is part of every action's cache key. This prevents stale
# remote cache entries from being reused after an Xcode update.
# Only needed on runners that do mactools builds (Mac/Sparkle). Non-Mac builds
# don't run this script; their apple_cc_autoconf stays cached because none of
# its environ vars change, so they're unaffected by Xcode version changes.
#
# 1. Writes .bazelrc.xcode with mactools-scoped flags:
# - action_env for remote cache key invalidation
# - DEVELOPER_DIR pointing to the active Xcode
#
# 2. Runs `bazel clean --expunge` when the version actually changes, because
# local_config_xcode (a cached repository rule) bakes in the old version
# local_config_apple_cc (a cached repository rule) bakes in the old version
# and can only be refreshed by clearing the output base.
