Allow array size to be a module-scope constant

Browse Source 
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.
