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.
