D3D11 only supports HLSL SM5.0 which doesn't support `space`
(binding group in WGSL). So for D3D11, only one binding group will be
used, and tint will not emit `space` for HLSL, so shaders can be used
with D3D11.

Change the DecomposeMemoryAccess to behave more like the DirectVariableAccess transform, in that it'll inline the access of buffer variable into the load / store helper functions, instead of passing the array down.
This avoids large array copies observed with FXC, which can have *severe* performance costs.

This CL removes the following AST nodes:
* ast::Array
* ast::Atomic
* ast::Matrix
* ast::MultisampledTexture
* ast::Pointer
* ast::SampledTexture
* ast::Texture
* ast::TypeName
* ast::Vector
ast::Type, which used to be the base class for all AST types, is now a
thin wrapper around ast::IdentifierExpression. All types are now
referred to using their type name.
The resolver now handles type resolution and validation of the types
listed above based on the TemplateIdentifier arguments.
Other changes:
* ProgramBuilder has undergone substantial refactoring.
* ProgramBuilder helpers for type inferencing is now more explicit.
Instead of passing 'nullptr', a new 'Infer' template argument is
passed.
* ast::CheckIdentifier() is used for more tests that check identifiers,
including types.

Enables the 'chromium_experimental_full_ptr_parameters' extension to
allow passing of uniform, storage and workgroup address-spaced
pointers as parameters, as well as pointers into sub-objects.
