5a48c0da15 SPIRV-Tools support for SPIR-V 1.5 (#2865)
* Ensure same enum values have consistent extension lists

* val: fix checking of capabilities

The operand for an OpCapability should only be
checked for the extension or core version.
The InstructionPass registers a capability, and all its implied
sub-capabilities before actually checking the operand to an
OpCapability.

* Add basic support for SPIR-V 1.5

- Adds SPV_ENV_UNIVERSAL_1_5
- Command line tools default to spv1.5 environment
- SPIR-V 1.5 incorporates several extensions.  Now the disassembler
  prefers outputing the non-EXT or non-KHR names.  This requires
  updates to many tests, to make strings match again.
- Command line tests: Expect SPIR-V 1.5 by default

* Test validation of SPIR-V 1.5 incorporated extensions

Starting with 1.5, incorporated features no longer require
the associated OpExtension instruction.

Implement WebGPU->Vulkan initializer conversion for 'Function' variables (#2513)
WebGPU requires certain variables to be initialized, whereas there are
known issues with using initializers in Vulkan. This PR is the first
of three implementing a pass to decompose initialized variables into
a variable declaration followed by a store. This has been broken up
into multiple PRs, because there 3 distinct cases that need to be
handled, which require separate implementations.

This first PR implements the basic infrastructure that is needed, and
handling of Function storage class variables. Private and Output will
be handled in future PRs.

This is part of resolving #2388

Add --strip-atomic-counter-memory (#2413)
Adds an optimization pass to remove usages of AtomicCounterMemory
bit. This bit is ignored in Vulkan environments and outright forbidden
in WebGPU ones.

Fixes #2242
