Cherry Mui 32851587d1 cmd/go: add PGO auto mode 
Add "auto" mode for the -pgo build flag. When -pgo=auto is
specified, if there is a default.pgo file in the directory of the
main package, it will be selected and used for the build.

Currently it requires exactly one main package when -pgo=auto is
specified. (We'll support multiple main packages in the future.)

Also apply to other build-related subcommands, "go install", "go
run", "go test", and "go list".

For #55022.
