Add SPV_NV_bindless_texture support (#8534)
Treat DescriptorHandle as uint64_t instead of uint2. Implement
target-specific SPIR-V emission with the bindless texture support.
For OpImageTexelPointer, Image must have a type of OpTypePointer with
Type OpTypeImage. Fix the issue by using [constref] in __subscript.
Add a test coverage for various texture/sampler handle types.
