d7e6f116f4 [mlir][spirv] Enhance structure type member decoration handling
Modify structure type in SPIR-V dialect to support:
1) Multiple decorations per structure member
2) Key-value based decorations (e.g., MatrixStride)

This commit kept the Offset decoration separate from members'
decorations container for easier implementation and logical clarity.
As such, all references to Structure layoutinfo are now offsetinfo,
and any member layout defining decoration (e.g., RowMajor for Matrix)
will be add to the members' decorations container along with its
value if any.

a290c3af9d [mlir][spirv] Improve stride support in array types
This commit added stride support in runtime array types. It also
adjusted the assembly form for the stride from `[N]` to `stride=N`.
This makes the IR more readable, especially for the cases where
one mix array types and struct types.

f741b8eabe [mlir][spirv] Move type checks from dialect class to type hierarchy
Types should be checked with the type hierarchy. This should result in
better responsibility division and API surface.

308571074c Mass update the MLIR license header to mention "Part of the LLVM project"
This is an artifact from merging MLIR into LLVM, the file headers are
now aligned with the rest of the project.

4562e389a4 NFC: Remove unnecessary 'llvm::' prefix from uses of llvm symbols declared in mlir namespace.
Aside from being cleaner, this also makes the codebase more consistent.

bd485afda0 Introduce attributes that specify the final ABI for a spirv::ModuleOp.
To simplify the lowering into SPIR-V, while still respecting the ABI
requirements of SPIR-V/Vulkan, split the process into two
1) While lowering a function to SPIR-V (when the function is an entry
   point function), allow specifying attributes on arguments and
   function itself that describe the ABI of the function.
2) Add a pass that materializes the ABI described in the function.

Two attributes are needed.
1) Attribute on arguments of the entry point function that describe
   the descriptor_set, binding, storage class, etc, of the
   spv.globalVariable this argument will be replaced by
2) Attribute on function that specifies workgroup size, etc. (for now
   only workgroup size).

Add the pass -spirv-lower-abi-attrs to materialize the ABI described
by the attributes.

This change makes the SPIRVBasicTypeConverter class unnecessary and is
removed, further simplifying the SPIR-V lowering path.

54a8473470 Makes spv.module generated by GPU->SPIRV conversion spec compliant
Makes the spv.module generated by the GPU to SPIR-V conversion SPIR-V
spec compliant (validated using spirv-val from Vulkan tools).

1) Separate out the VulkanLayoutUtils from
DecorateSPIRVCompositeTypeLayoutPass to make it reusable within the
Type converter in SPIR-V lowering infrastructure. This is used to
compute the layout of the !spv.struct used in global variable type
description.
2) Set the capabilities of the spv.module to Shader (needed for use of
Logical Memory Model, and the extensions to
SPV_KHR_storage_buffer_storage_class for use of Storage Buffer)
