Add the unit tests samples from src/reader/spirv when:
- they are valid for Vulkan 1.0 (plus some common extensions)
- they should translate to valid WGSL

David Neto 889b77a2a1 writer: avoid type breakage during AppendVector 
When building a vector via tint::writer::AppendVector, and the
vector argument is already a vector constructor, expand that
vector constructor into its components only when those components
are all scalars.  This avoids a type breakage which can occur with cases
like this:

 vector argument is:
	  vec2<i32>(vec2<u32>(0u,1u))
 scalar argument is:
          2

Before this fix, the result was:
  vec2<i32>(0u, 1u, 2);

But should be this instead:
  vec3<i32>(vec2<u32>(0u,1u),2)

This was noticed in SPIR-V writer output when forming a coordinate
vector from a an unsigned WGSL coordinate vector with a signed array
vector.

Fixed: tint:1048
