Ben Clayton 1a1b5278d5 tint/transform: Inline HLSL uniform / storage buffers
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.

Ben Clayton 971318f7a2 tint: Replace all remaining AST types with ast::Type
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.

Ben Clayton 6992f51ebd tint: Add DirectVariableAccess transform
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.
