This CL makes it clearer where errors are coming from and fixes the

For a swizzle with one element (eg vec.x) the result type is just the
type of the vector, instead of a new vector.

(I expect that) the WGSL signed division operator expects both operands
to be signed and the result will also be signed.
When the operands of a SPIR-V OpSDiv is unsigned, then wrap
the operand in an as-cast to the corresponding signed type.
When the result type of a SPIR-V OpSDiv instruction is unsigned,
we have to wrap the generated WGSL operator with an as-cast to
that unsigned type.
This first CL addresses OpSDiv. We'll address other operations in future CLs.

The AST only wants expressions, not their result types.
But the SPIR-V reader wants to track the AST type as well.
So introduce a TypedExpression concept for internal use.

This CL adds support to the type determiner for the GLSL Radians and
Degrees methods. We use the general float calls for this because we only
support FP32 and have plans for FP16. Other floating point sizes are not
supported but we have no support for them..
