…ld#1685) This adds two flags to the `fix` and the `update` command, `-cpuprofile` and `-memprofile`, which allow users to create output CPU and memory `pprof` files to better understand the performance of Gazelle. This is very helpful in debugging issues like bazelbuild#1688, which show up in certain repository setups. The implementation mostly followed the instructions on https://pkg.go.dev/runtime/pprof#hdr-Profiling_a_Go_program to set up profiling options for the command in the `cmd/gazelle`. Tests were added to ensure that the `newProfile` would return a `profile{}` that wouldn't panic, even if either provider is empty. Co-authored-by: Fabian Meumertzheim <fabian@meumertzhe.im>
