[CPP] Unable to pass SIzeVerifier to root verifier

[thejtshow]

It looks like FLATBUFFERS_TRACK_VERIFIER_BUFFER_SIZE was deprecated, the ability to call either of the following was broken:

flatbuffers::SizeVerifier verifier{ data, len };

verifier.VerifyBuffer<my_root_type>(); // compiler error

auto my_buffer = Getmy_root_type(data);

my_buffer->Verify(verifier); // compiler error

[thejtshow]

these both fail with some flavor of

verifier.h:216:64: error: cannot convert 'flatbuffers::VerifierTemplate<true>' to 'flatbuffers::Verifier&' {aka 'flatbuffers::VerifierTemplate<false>&'}
