cmd/go: add -pgo build flag
Add a -pgo flag for "go build" (and other build actions), to
specify the file path of a profile used for PGO. Special name
"off" turns off PGO.
The given profile path is passed to the compiler.
The build cache is sensitive to the content of the given PGO
profile.
TODO: auto mode.
For #55022.
