Normal behavior of ApiObjectBase's APIRelease() which only locks the
device when last ref dropped is not thread safe if the object is cached
as raw pointers by the device. Example of cached objects: bind group
layout, pipeline, sampler, shader module.
The following scenario could happen:
- thread A:
- shaderModuleA.APIRealease()
- shaderModuleA.refCount.Decrement() == true (ref count has reached zero)
- going to call shaderModuleA.LockAndDeleteThis().
- thread B:
- device.CreateShaderModule().
- lock()
- device.GetOrCreateShaderModule()
- shaderModuleA is in the cache, so return it.
- unlock()
- thread A:
- starting to call shaderModuleA.LockAndDeleteThis()
- lock()
- erase shaderModuleA from the cache.
- delete shaderModuleA.
- unlock()
This CL disables caching when ImplicitDeviceSynchronization is turned on
until we find a better solution.

Currently the `is_reserved` method in the WGSL parser uses the
`operator==` on the token to check the reserved words. This ends up
re-doing a bunch of work as it checks the token type, then gets the
`string_view` or `string` from the variant, then compares.
This CL adds a precondition that the token is an identifier (which is
true in the only case we call this method) and then extracts the string
from the token once and uses that for all the comparisons.

Some of the benchmark shaders when run with the MSL backend are

This Cl adds some default configuration to the MSL bench to make a slot

such that all shaders work correctly.
