Recent changes to DecomposeMemoryAccess meant we lost the dependency information between the user of a module-scope variable of the storage / uniform address space and the variable.
Add dependency information to ast::InternalAttribute so this can be tracked.
This change also means that symbol renaming after the DecomposeMemoryAccess should work.

In order to preserve padding properly for MSL, we need to use its
packed_vec type for all vec3 types in storage buffers, not just struct
members. This commit includes a complete rewrite of the PackedVec3
transform to achieve this. The key details are:
* An internal `__packed_vec3<>` type was added, which corresponds to a
`type::Vector` with an additional flag to indicate that it will be
emitted as packed vector.
* The `PackedVec3` transform replaces all vec3 types used in
host-shareable address spaces with the internal `__packed_vec3`
type. This includes vec3 types that appear as the store type of a
pointer.
* When used as an array element, these `__packed_vec3` types are
wrapped in a struct that contains a single `__packed_vec3`
member. This allows us to add an `@align()` attribute that ensures
that `array<vec3<T>>` still has the correct array element stride.
* When the `vec3<T>` appears as a struct member in the input program,
we apply the `@align()` to that member to ensure that we do not
change its offset.
* Matrix types with three rows that are used in memory are replaced
with an array of columns, where each column uses a `__packed_vec3`
inside an aligned wrapper structure as above.
* Accesses to host-shareable memory that involve any of these types
invoke a "pack" or "unpack" helper function to convert them to the
equivalent type that uses `__packed_vec3` or a regular `vec3` as
required.
* The `chromium_internal_relaxed_uniform_layout` extension is used to
avoid issues where modifying a type in the uniform address space
triggers stricter layout validation rules.

* ast::Pointer
* ast::SampledTexture
* ast::Texture
* ast::TypeName

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.
