As the resolver currently enforces in-order declarations, this does not
change the declaration order from iterating over the
ast::Module::GlobalDeclarations.
The MSL backend has been changed to use the
sem::Module::DependencyOrderedDeclarations list instead of looping over
different declaration types separately.

This removes a lot of awkward logic from the MSL writer, and means
that we now handle all module-scope variables with the same transform.

Inline the `continuing` block in the places where `continue` is called.
Simplifies the emission, and fixes emission of `let` statements in the loop.
This fix matches the same approach in writer/hlsl.

Some now pass, some still fail.
If we fix bugs and they begin to pass, we have a better chance of noticing and marking the issues as fixed.
