Expanded gfx::Format to include additional formats (#1982)

* Format list updated with additional formats supported by both D3D and Vulkan; D3DUtil::getMapFormat() and VkUtil::getVkFormat() updated to include additional formats; GFX_FORMAT() updated with all additional formats (BC compression unfinished)

* Finished updating GFX_FORMAT with newly added formats and sizes; Pixel size is now tracked using the FormatPixelSize struct containing the values for bytes per block and pixels per block to accomodate BC formats; Updated gfxGetFormatSize and associated sub-calls to return FormatPixelSize instead of uint8_t; Most calls to gfxGetFormatSize() updated to reflect changes, a couple calls still unupdated

* Changes to accommodate new formats finished, debugging slang-literal unit test

* First format unit test working

* One test added for BC1Unorm and RGBA8Unorm_SRGB, both passing

* Refactored format testing code to merge BC1Unorm and RGBA8Unorm SRGB into a single file

* All unit tests added for BC and Srgb formats

* Most tests added and working; Added five additional formats (still need tests) and made the appropriate changes to support these; createTextureView() modified for D3D11, D3D12, and Vulkan to take into account the format specified in the texture view desc when the texture's format is typeless

* Format enums renamed to more closely match their D3D counterparts; Added a universal float and uint buffer and buffer view for use across all Format tests

* Remaining tests added; D3D12 tests pass, but Vulkan crashes in BC1_UNORM and D3D11 spits out a bunch of D3D11 Errors (but supposedly passes)

* re-run premake

* Added Sint versions of test shaders; Vulkan and D3D11 tests also pass

* Size struct for format unit tests no longer use initializer lists

* Fixed a Size struct missed in the previous pass

* Fixed minor bugs causing tests to fail

* Added documentation detailing all currently unsupported formats

* Skip tests causing unsupported format warnings due to swiftshader

* updated several test using old Format enum names

* Revert change to compareComputeResult() that was added for debugging purposes

* DEBUGGING: Added prints to identify which formats are failing on CI

* Reverted attempted debugging changes; Fixed texture2d-gather.hlsl to use updated Format enums

* Fixed incorrect array sizes in d3d11 _initSrvDesc()

* Commented out further tests that produce unexpected results when tested for Vulkan with swiftshader

* Revert "Merge branch 'expanded-format-support' of https://github.com/lucy96chen/slang into expanded-format-support"

This reverts commit 20008f0d3ecc3b1405ecac8c138edaa3cd37ed6b, reversing
changes made to 6081e95827315fee50e18409394d5abd62fac787.

* Added a fuzzy comparison function for use with floats

* submodule update

* Revert messed up changes caused by previous revert after automatically merging on github

+Unsupported Formats
+======================
+GFX currently does not support the following listed D3D and Vulkan formats. With the exception of D24_UNORM_S8_UINT, these formats have been omitted as their counterpart API does not have a corresponding format. D24_UNORM_S8_UINT has been omitted as it is only supported by Nvidia.
