Validate run_constrained specs

[jaimergp]

Description

Closes #5047

conda-build allows to include run_constrained items in the recipe content. These are sometimes not checked because they only affect the solver if the constrained name happens to be present in the test environment. As a result, faulty lines might get sneak all the way into the final repodata.json.

When the rules finally kick in, you get a solver error. One current example comes in the willow recipe, which constrains pillow-heif.

That line is not a valid MatchSpec:

>>> from conda.models.match_spec import MatchSpec
>>> MatchSpec("pillow-heif >=0.10.0,<1.0.0<py312|>=0.13.0,<1.0.0>=py312")

This PR adds a check for all run_constrained item to make sure they don't ever reach a final package without getting it addressed.
