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.

Change Resolver::Expression() and Resolver::Identifier() to return a

This is required as IdentifierExpressions may resolve to non-values.
Handle expressions that resolve to types, when they are expected to

The resolver now wraps sem::Expression objects with a sem::Load object
anywhere that the load rule is invoked. sem::Expression provides an
`UnwrapLoad()` method that returns the inner expression (or
passthrough, if no load is present), which is analaguous to
Type::UnwrapRef().
The logic for alias analysis in `RegisterLoadIfNeeded` has been folded
into the new `Resolver::Load` method.
Fixed up many transforms and tests. The only difference in output is
for a single SPIR-V backend test, where some IDs have changed due to
slight re-ordering of when expressions are generated.
There may be further clean-ups possible (e.g. removing unnecessary
calls to `UnwrapRef`, and simplifying places in the SPIR-V writer or
transforms that deal with memory accesses), but these can be addressed
in future patches.

Expand the Option argument paradigm to:
* Remove the requirement to always pass a 'type' parameter. Type inferencing is the easier, and increasingly common way to declare a variable, so this prevents a whole lot of `nullptr` smell which negatively impacts readability.
* Accept attributes directly as arguments, removing the `utils::Vector{ ... }` smell.
Rename `ProgramBuilder::VarOptionals` to `VarOptions`, and add equivalent `LetOptions`, `ConstOptions` and `OverrideOptions`.
Clean up all the calls to `Var()`, `Let()`, `Const()` and `Override()`:
* Use the `Group()` and `Binding()` helpers where possible
* Removing `nullptr` type arguments
* Replace attribute vectors with the list of attributes.
* Remove already-defaulted `ast::StorageClass::kNone` arguments.
* Remove already-defaulted `ast::Access::kUndefined` arguments.
Finally, remove the `GroupAndBinding()` helper, which only existed because you needed to pass attributes as a vector.

When enabling the SPIR-V reader or SPIR-V writer we were suppressing
-Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables
for the `libtint` cmake target and anything that depended on that
target. Because we'd build all readers/ writers by default this caused
us to never hit those warnings.
A recent change to the cmake build sets the Tint backend based on
the Dawn backend. So, there is a much higher chance of not building
the SPIR-V support if you're on a Mac or Windows machine.
This CL removes the suppression of the warnings, adds specific pragmas
into the SPIR-V reader code which imports the SPIRV-Tools headers
and fixes up the warnings which were then firing due to checking
for the new warnings.
