Antonio Maiorano 39a65a1d1e Add type inference support to Resolver
There is still no way to spell this out in WGSL, but this adds support
for VariableDecls with an ast::Variable that has nullptr type. In this
case, the Resolver uses the type of the rhs (constructor expression),
which is stored in semantic::Variable.

Added tests for resolving inferred types from constructor, arithmetic,
and call expressions.
