LOG: [clang][NFC] Bump the maximum number of Frontend diagnostics (#210345)

The number of Frontend diagnostics in DiagnosticFrontendKinds.td is
close to the DIAG_SIZE_FRONTEND limit of 200 (195 in use), and in-flight
PRs adding frontend diagnostics (e.g. #187986) run into the static
assert in DiagnosticIDs.cpp. Increase the limit to 300, following the
precedent of #200948 which did the same for Sema diagnostics.
