Previously the Clone() of the AST would clone all the functions, globals
and type declarations in a temporary vector, then assign this to the
ast::Module. This meant that adding new module-scope declarations inside
callbacks of ReplaceAll() would place them right at the top, before any
of the cloned declarations.
As top-level declarations are not statements, ensuring that a new object
comes before the current ReplaceAll() declaration is surprisingly
tricky.
With this change, we can now safely assume that calling
ProgramBuilder::Var(), ProgramBuilder::Func(), ProgramBuilder::Alias()
or ProgramBuilder::Structure() inside a ReplaceAll() will add that
module-scoped declaration before the currently processed top-level
declaration.

And fix issues where global variables would not be emitted unless they were transitively referenced by an entry point.

validation for them.
Emit [[texture()]] and [[sampler()]] attributes on these entry point

When moving private and workgroup variables into the entry point,
generate pointers to pass as arguments to sub-functions on demand,
instead of upfront. This removes a bunch of unnecessary dereferences
for accesses inside the entry point, and one function variable.

arrayLength() will take a pointer to a storage buffer array.
This pointer may pass through function scoped let statements.
To make this intrinsic easier to generate, inline the pointer lets and
remove chains of &*&*.

When generating the store type for a variable, follow SPIR-V
instructions directly. Avoid using the SPIRV-Tools optimizer because
it deduplicates structures that differ only in non-semantic annotation (e.g. member names)

TypeDecls (alias, structure) are not a types - they declare types.
ast::TypeName is what's used for a ast::Type.
Previously we were trying to automatically convert these to TypeNames in the builder, but having these inherit from ast::Type was extremely error prone.
reader/spirv was actually constructing ast::Structs and using them as types, which is invalid.

Add a Resolver::IsPlain() method to check for plain types, which is
then used instead of IsStorable() for validating array and struct
subtypes.
Remove validation of assignment and constructor RHS types, instead
validating the type of the variable declaration. This catches
additional errors that were previously missed, such as using a pointer
for a var declaration with no constructor.
