... once the maximum number of errors have been reached.
https://dawn-review.googlesource.com/c/tint/+/56070 introduced maybe_set_synchronized(), which only set synchronized_ when the number of errors reported was less than max_errors_, but it seems the fuzzers have found ways to generate an excessive number of errors that keep the parser synchronized.
Revert 56070, and instead check the synchronized state along with the error count for every unbounded loop in the parser.

This CL removes the old token `Is<Name>()` methods which are no longer
being used in the parser or lexer. (Some of them were used in tests but
the generic `Is(<type>)` is used instead.
New `peek` methods are added which will peek if the given token comes
either next or at the given index.

As all loops in the parser require `synchronized_` to be true, don't set this to true if we've hit the maximum number of error diagnostics.
This lets the parser bubble up as soon as the limit was reached, instead of only aborting once we finally reach the top level loop.
ClusterFuzz has uncovered a number of cases where, in a loop, it can produce an error, then resynchronize, then error again on the next loop iteration. This produces more than the max limit of errors, and can stall the tests long enough to time out.
No unit tests for this, as it requires a really contrived input to trigger, and to exhaustively catch all the places we now call maybe_set_synchronized() would result in a large colleciton of horrible tests. Instead, let ClusterFuzz do the testing.
