Add built in runtime deployer

[fdgStilla]

Fix https://github.com/conan-io/conan/issues/15381

This PR is currently a draft, only tested manually on windows with:

conan install --requires=zlib/1.3 --requires=cmake/3.28.1 -of C:\Users\florian.degaulejac\tmp\zlib-cmake --deployer runtime_deploy.py -vtrace --deployer-folder C:\Users\florian.degaulejac\tmp\zlib-cmake\deploy -o "zlib/*:shared=True"

Remaining tasks that I won't have the time to complete:

• [ ] write autotest instead of manual test
• [ ] test other env (linux, apple...)
• [ ] symbolic links
• [ ] test with deep hierarchy and check it is flatten

And a weird behavior I observed: dep.cpp_info.bindirs and dep.cpp_info.libdirs are populated with absolute paths instead of relative path like described in the documentation.

Do you think you could add some basic, simple test? Or do you want me to contribute it? No prob, I can help with that.

I am currently struggling to migrate all our projects to conan 2 and I won't have the time to do work more to this PR so any contribution is more than welcome!

Hello @memsharded,

Do you have time to keep working on this? I think it could come in very handy for many people. Thanks a lot

[memsharded]

Sorry for the delay, things have been a bit busy, and this was stuck in the backlog.

I have added some missing things:

• Components support
• Output scope
• Avoid unnecessary copies to speed up repeated deploys

Ready to move this for next 2.5

[memsharded]

Done, added docstrings.

I'm kind of surprised this was included in the 2.5.0 release with the two major bugs still present (.so files and symlinks are currently broken, #16527).
