[libcxx][test] Create feature host-can-create-symlinks (llvm#82204)

On Windows you can not create symlinks without elevated privileges
unless you have Windows developer mode enabled. There's ~67 libcxx tests
that run into failures on windows if your environment is not set up
correctly (Go to windows settings and enable "developer mode").

This change:
- Adds a feature check for whether the host can create symlinks. (see
libcxx/utils/libcxx/test/features.py)
- Mark the feature as required for the 67 tests that hit failures on
windows due to this. This will allow lit to correctly mark these tests
as unsupported instead of unexpectedly failed (this is helpful since
then you know you didn't break something with your change, it's just
that it's not supported with your environment).
