Removes uniformity bit from resource initialization intrinsics `llvm.{dx|spv}.resource.handlefrombinding` and `llvm.{dx|spv}.resource.handlefromimplicitbinding`. The flag currently always set to `false`. It should be derived from resource analysis and not provided by codegen.
Closes#135452
Adds resource name argument to `llvm.dx.handlefrombinding` and `llvm.dx.handlefromimplicitbinding` intrinsics.
SPIR-V currently does not seem to need the resource names so this change only affects DirectX binding intrinsics.

We can end up with loads of single element vectors when we have scalar
values, because the vectorizer may introduce these to use ops like
shufflevector in some cases. Make sure we're maintaining the correct
type when translating these into resource load operations.
Fixes#136409.
We'd introduced separate versions of `llvm.dx.resource.load` with a
struct return to handle the CheckAccessFullyMapped case without making
the IR for the common case unnecessarily complicated. However, at this
point the common case is really `resource.getpointer`, so the ergonomics
of a simplified version of `load` don't actually gain us as much as the
cost of having multiple opcodes.
Drop the `dx.resource.loadchecked` functions and have `dx.resource.load`
consistently return `{element_type, i1}`.
