Error if super-type capabilities are a super-set of sub-type (#7452)
Fixes: #7410
Changes:
1. super-type capabilities must be a super-set of sub-type capabilities
(and support the same shader stages/targets)
* InheritanceDecl visits super-type to inherit it's capabilities;
validate InheritanceDecl capabilities against sub-type
* visit all container decl's with a default case
* clean up functionDeclBase visitor
* Simplify `diagnoseUndeclaredCapability` by moving logic into
capability checking (more correct*)
3. added changed behavior to documentation
4. fixed some incorrect capabilities
5. **we do not** diagnose capability errors on interface
requirement-to-implementation if both lack explicit capability
requirements. This change is to work around a slangpy regression (test
case for the failing situation is in
`tests\language-feature\capability\capability-interface-extension-1.slang`),
Note: maybe for slang-2026 we don't do this?
6. requirement & implementation must support the same shader
stage/target. This was changed because otherwise we can have cases where
`X` inherits from `Y`, but `Y` is only expected to be used in `glsl`
whilst `X` is expected to be used in `hlsl | glsl`
7. removed
`tests/language-feature/capability/capabilitySimplification3.slang`
because it tests nothing special (redundant)
Note: not using rebase due to separate branches depending on this PR
