Texture buitins on depth textures always result in scalar f32.
Corresponding operations in SPIR-V always result in vec4<f32>.
When translating to Tint AST, wrap the generated texture builtin
in a type constructor to vec4, with the builtin result as the
x component.

The interface for cloning a module was made significantly more complex in https://dawn-review.googlesource.com/c/tint/+/35502/ as some of the transforms required constructing symbols before the clone. This was temporary solution in 35502 was to copy the symbol table, then construct the new types, then perform the clone. This lead to a really messy callback interface, that was extremely error prone (e.g. lamda-capturing stack variables from the initializer callback that had been unwound).
Instead, clone the symbols as they're encountered. This may produce an entirely different set of identifiers, but no longer ever-grows the symbol list, and keeps the interface clean.
