new lock remove command

[memsharded]

Changelog: Feature: New conan lock remove command to remove requires from lockfiles.
Docs: conan-io/docs#3496

I am proposing this PR to close:

Close #14523
Close #14524

The idea is that updates are equivalent to something like:

$ conan remove --requires=zlib/* && conan add --requires=zlib/1.2.11

But it will allow us to first iterate and learn about the logic of removal of versions from lockfiles, because conan remove makes sense in isolation, even without lock update or lock add, like for example using it before resolving it to latest with --lockfile-partial. When we have clear what is the UX and UI for the removal, we can do a single command conan update or conan add with extra arguments

Nice! Only have 1 doubt about a pattern case, otherwise looks good to me
