  [AMDGPU][NFC] Allow selected generic features on any covered GPU

Add AMDGPUGenericAnyFeature so individual feature classes can require
support from at least one covered GPU. Check explicitly marked features
even when they are not frontend-visible, while retaining the all-member
check for ordinary frontend-visible features.

Follow implied features using their own validation rules. Require named
generic targets to cover at least one concrete AMDGPU GPU, rejecting self
references, other generic targets, pseudo targets, and invalid members.

Cover partial support, missing support, exact numeric-feature membership,
backend-only features, implications, and malformed coverage lists with
TableGen tests. Generated target definitions remain unchanged.
