text_format: enforce recursion limit for Any bracket syntax

[1seal]

this makes TextFormat::Parser::SetRecursionLimit() apply to google.protobuf.Any bracket syntax ([type.googleapis.com/...]{...}) by decrementing/ restoring recursion_limit_ around ConsumeAnyValue(), matching the normal nested-message paths.\n\nadds a regression test: TextFormatParserTest.SetRecursionLimitAnyBracketSyntax.\n\nfixes: #26195

Thanks for the contribution!

You can leave this as DO() and not interweave the return and recursion limit reset.

I can see its the preexisting pattern we don't restore the recursion limit in ConsumeFieldMessage() or SkipFieldMessage(), once we've failed there's not resuming and so unwinding the recursion limit isn't needed.

I'm clicking the rebase button in the github UI to unblock the cI

(Writing the comment to avoid any confusion; it has surprised folks in the past that I can update their branch, its a github feature where the branch can be set to allow the upstream maintainers to make commits exactly for this reason)

Unfortunately looks like the latest snapshot regressed the intended behavior (the newly added unit test now fails)

i tracked the post-rebase failure down to the new test expectation rather than the recursion-limit change itself. pushed a follow-up fix adjusting the reported error location for this case.
