A find or return-default utility.
Rename `find_or_replace.h` to `map.h` which contains both these utilties that operate on maps.

Ben Clayton 735dca8393 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.

The object is not always an array. The index can be applied to vectors
too.

Ben Clayton 8648120bbe Make all ast and sem pointers const
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.

Ben Clayton 4f3ff57c28 ast: Keep style consistent
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.

James Price 4cc4315d6c Allow array size to be a module-scope constant
Change ast::Array to use an ast::Expression for its `size` field. The
WGSL frontend now parses the array size as an `primary_expression`,
and the Resolver is responsible for validating the expression is a
signed or unsigned integer, and either a literal or a non-overridable
module-scope constant.

The Resolver evaluates the constant value of the size expression, and
so the resolved sem::Array type still has a constant size as before.

Also remove CloneWithStatementsAtStart().
CloneContext::InsertFront() is a better replacement.

Replaces arrays with an explicit stride with an array to a structure holding the element padded with a `[[size]]` decoration.
