Joe Tsai 44e4150b30 reflect/protoreflect: optimize Name.IsValid and FullName.IsValid 
For simplicity, IsValid was implemented in terms of regular expressions,
which are useful for verifying a string according to a strict grammar,
but performs poorly. Implement the check in terms of hand-written code,
which provides a 20x improvement to validate the name "google.protobuf.Any".

name               old time/op  new time/op  delta
FullNameIsValid-8   683ns ± 2%    35ns ± 1%  -94.86%  (p=0.000 n=10+10)
