Remove quic_ietf_framer_test.cc
gfe-relnote: n/a (test-only)
This file was originally removed in cl/285292619 but was accidentally added
back in cl/285401547. This file is still unnecessary and it isn't
referenced in any BUILD files.

-// gunit tests for the IETF-format framer --- generally does a simple test
-// for each framer; we generate the template object (eg
-// QuicIetfStreamFrame) with the correct stuff in it, ask that a frame
-// be serialized (call AppendIetf<mumble>) then deserialized (call
-// ProcessIetf<mumble>) and then check that the gazintas and gazoutas
-// are the same.
-//
-// We do minimal checking of the serialized frame
-//
-// We do look at various different values (resulting in different
-// length varints, etc)
