SPIR-V image operations (shader-slang#3163)

* Add __truncate and __sampledType for spirv_asm

Allows some texture tests to start passing

* add __isVector

Currently unused

* Add 1-vector legalization pass (WIP)

* Add capabilities for image types

* neaten instruction dumping

* add 1-vector test

* Add a couple of cases to vec1 legalization

* Remove texture tests from expected failures

* comment

* regenerate vs projects

* Remove redundant define form synchapi emulation

* refactoring image methods

* All sample functions refactored

* Remove incorrect glsl intrinsics

Partially addresses shader-slang#3174

* __subscript image ops via writing funcs

* Extract texture struct writing from core.meta.slang

* Abstract out cuda intrinsic

* Remvoe erroneous call to opDecorateIndex

* spirv asm IR utils

* Correct position of loads for SPIR-V asm inst operands

* Raise constructors to global scope during spir-v legalization

* Correct snippet output

* Implement most texture sampling ops for SPIR-V

* Legalize 1-vectors for glsl too

* Make SPIR-V inst operands non-hoistable

* Better 1-vector legalization

* Put textures in ptrs for spirv

* insert missing break

* Add vec1 legalization test

* Add some missing pieces to slang-ir-insts

* Greatly neaten vec1 legalization

* a

* Neaten vec1 legalization

* Add image read and write intrinsics for spir-v

* Squash warnings

* regenerate vs projects

* Drop redundant guards

* Drop 5 tests from expected failure list

* Inst numbering changes to cross compile tests

* vec1 legalization tests only on vk

* Correct location of asm op emit

* Inline constant in spirv-asm

* Correct signedness for lane in wave intrinsics

* Extract element from float1 for cuda

* squash warnings

* Neaten spirv-emit

* dedupe more capabilities

* warnings

* neaten assert

* comments
