Adds a vector<CastableBase*> to ast::Module which stores the list of
global variables, functions, and types, in the order that they were
declared.
This will be used to fix validation and backend issues around name
uniqueness.

Pull the mutable semantic field from ast::Identifier and into a new semantic nodes.
Have the TypeDeterminer create these new semantic nodes.
Note: This change also fixes the node that holds the semantic information for a call.
Previously this was on the identifier, and this is now correctly on the CallExpression.
The identifier of the CallExpression should resolve to the target function, not the return type.
Functions can currently be represented as a type, and the identifier of a CallExpression now has no semantic information.

The error was added to diagnostics_, and then this list was replaced with diagnostics from the builder.
This resulted in the error silently being dropped.

Remove the mutable `result_type` from the ast::Expression.
Replace this with the use of semantic::Expression.

Also demangle - this also reduces a bunch of copy-pasta code.

Will hold the mutable fields that currently reside in the otherwise immutable-AST.
Change the AST string methods to accept a `const semantic::Info&`. This is required as some nodes include type-resolved information in their output strings.

By putting diagnostics into the program, we can hold all the diagnostic messages for parsing and type determination in one place.
This also means that we can simplify the public WGSL and SPIR-V Parser interfaces to a single function.

Program is now immutable*, and remains part of the public Tint
interface.
ProgramBuilder is the mutable builder for Programs, and is not part of
the public Tint interface. ast::Builder has been folded into
ProgramBuilder.
Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().
Mutable ProgramBuilders can be moved into immutable Programs.
* - mostly immutable. It still has a move constructor and move
assignment operator - required for practical usage - and the
semantic information on AST nodes is still mutable.

Enforce all places where Dawn passes in or returns a ast::Module, now takes a `const Program* ` or returns a `Program`.
As the end goal of all this is to have immutable Programs, all Program inputs take a pointer instead of moving the actual object.
As consumers of a Program are now all const, we have to const_cast to work around all the places we've been incorrectly mutating a ast::Module.
These const_casts are temporary, and will be fixed in the next set of changes.
