resolver: Fix constant propagation for POC

Pipeline overidable constants are not compile-time constant.
If a module-scope const has an [[override]] decoration, do not assign
the constant value to it, as this will propagate, and the constant value
may become inlined in places that should be overridable.

Also: Rename sem::GlobalVariable::IsPipelineConstant() to
IsOverridable() to make it clearer that this is not a compile-time known
value. Add SetIsOverridable() so we can correctly set the
IsOverridable() flag even when there isn't an ID.
