This change implements the behavior analysis for expressions and
statements as described in:

This CL makes no changes to the validation rules. This will be done as a
followup change.

To fix this, we trick the compiler by wrapping the function body with an
if (true) { <function body> } followed by returning an unused value of
the return type.

The semantic nodes cannot be fully immutable, as they contain cyclic
references. Remove Resolver::CreateSemanticNodes(), and instead
construct and mutate the semantic nodes in the single traversal pass.
Give up on trying to maintain the 'authored' type names (aliased names).
These are a nightmare to maintain, and provided limited use.
Significantly simplfies the Resolver, and allows us to generate more
semantic to semantic references, reducing sem -> ast -> sem hops.
Note: This change introduces constant value propagation across constant
variables. This is unlocked by the earlier construction of the
sem::Variable.

Rename workgroup_size() to WorkgroupSize().
Remove the return_statements. These were not used anywhere.

And remove a whole load of const_cast hackery.
Semantic nodes may contain internally mutable fields (although only ever modified during resolving), so these are always passed by `const` pointer.
While all AST nodes are internally immutable, we have decided that pointers to AST nodes should also be marked `const`, for consistency.
There's still a collection of const_cast calls in the Resolver. These will be fixed up in a later change.

Methods and functions are `CamelCase()`
Public fields are `snake_case` with no trailing `_`
Private fields are `snake_case` with a trailing `_`
Remove pointless getters on fully immutable fields.
They provide no value, and just add `()` noise on use.
Remove unused methods.

The workgroup size should not be a property of the function in the
AST, and this lays the groundwork for allowing both literals and
module-scope constants to be used for this attribute.

Not currently called (nothing currently attaches ast::Type nodes to the AST), but implements some of the boilerplate that'll be shortly required.
This change also removes a bunch of duplicated enumerators from the sem namespace for their counterpart in the ast namespace.
