cargo: add release-lto profile

Browse Source 
The idea is to build ripgrep with as much optimization as possible.

This makes compilation times absolutely obscene. They jump from <10
seconds to 30+ seconds on my i9-12900K. I don't even want to know how
long CI would take with these.

I tried some ad hoc benchmarks and could not notice any meaningful
improvement with the LTO binary versus the normal release profile.
Because of that, I still don't think it's worth bloating the release
cycle times.

Ref #1225
