ast: Remove TypeConstructorExpression 

Add a new 'Target' to the ast::CallExpression, which can be either an
Identifier or Type. The Identifier may resolve to a Type, if the Type is
a structure or alias.

The Resolver now resolves the CallExpression target to one of the
following sem::CallTargets:
* sem::Function
* sem::Intrinsic
* sem::TypeConstructor
* sem::TypeCast

This change will allow us to remove the type tracking logic from the WGSL
parser, which is required for out-of-order module scope declarations.
