Koichi Shiraishi 88b8a16089 cmd/cover: replace code using optimized golang.org/x/tools/cover 
After CL 179377, this change deletes all the prior cmd/cover code
and instead vendors and type aliases code using the significantly
optimized  golang.org/x/tools/cover, which sped up ParseProfiles by
manually parsing profiles instead of a regex. The speed up was:

name         old time/op   new time/op   delta
ParseLine-12 2.43µs ± 2%   0.05µs ± 8%   -97.98% (p=0.000 n=10+9)

name         old speed     new speed       delta
ParseLine-12 42.5MB/s ± 2% 2103.2MB/s ± 7% +4853.14% (p=0.000 n=10+9)

Fixes #32211.
