Capability System: Implicit capability upgrade warning/error (#4241)

* capability upgrade warning/error

adjusted implementation + tests to support a warning/error if capabilities are implicitly upgraded and test accordingly.

* add glsl profile caps

* add GLSL and HLSL capabilities to the associated capability

* syntax error in capdef

* only error if user explicitly enables capabilities

1. changed testing infrastructure to not set a `profile` explicitly,
2. Added tests to be sure this works as intended with user API and with slangc command line

* Change capability atom definitions and how Slang manages them to fix errors

1. most `glsl_spirv` version atoms have been removed from `.capdef`, instead we will translate `spirv` version atoms into `glsl_spirv` since there is no point in writing the same code twice in `.capdef` files to define `spirv` versions.
2. add spirv version, and hlsl sm version (and equivlent) capability dependencies
3. removed some stage requirments which were set on objects, keep the wrapper capabilities. I am keeping the wrapper capabilities since I am unaware on if there are stage limitations (spec says code in practice does not work).

* check internal version instead of version profile (_spirv_1_5 vs. spirv_1_5)

* remove unused OpCapability. adjust SPIRV version'ing again for glsl_spirv

* apply workaround for glslang bug with rayquery usage

* ensure capabilities targetted by a profile and added together by a user are valid

* remove additions to `spirv_1_*` wrapper

* spirv_* -> glsl_spirv fix

* fix bug where incompatable profiles would cause invalid target caps

* try to avoid joining invalid capabilities

* fix the warning/error & printing

* run through tests to fix capability system and test mistakes

many mistakes were mesh shaders doing `-profile glsl_450+spirv_1_4`. This is not allowed for a few reasons
1. the test tooling does not handle arguments the same as `slangc`
2. glsl_450 core profile does not support mesh shaders, nor does spirv_1_4. sm_6_5 does work in this senario

* set some sm_4_1 intrinsics to sm_4_0

* replace `GLSL_` defs with `glsl_`

* swap the unsupported render-test syntax for working syntax

* set d3d11/d3d12 profile defaults

this is required since sm version changes compiled code & behavior

* adjusted nvapi capabilities with atomics + d3d11 set to use sm_5_0 as per default

* cleanup

* address review

* incorrect styling

* change `bitscanForward` to work as intended on 32 bit targets
