Commit Message

xds: fix TSAN data races in xDS security components and tests (#12829)

This change resolves several data races reported by ThreadSanitizer
(TSAN) in XdsSecurityClientServerTest and associated xDS security
components.

Key changes:
- Made certificate, key storage, and SSL context fields volatile in
CertProviderSslContextProvider and DynamicSslContextProvider to ensure
safe publication between Netty EventLoop threads and background
FileWatcher threads.
- Made experimental static flags (enableSpiffe and
useChannelAuthorityIfNoSniApplicable) volatile. These flags are toggled
by tests while being read by background networking threads; making them
volatile ensures these transitions are thread-safe and TSAN-compliant.
