QShaderGenerator didn't handle substitutions like
`vec4 $color = mix($color1, $color2, $fac);`
Note that `$color` is a prefix to `$color1` and `$color2`. For the
substitution `QByteArray::replace` was used so if `$color` was handled
first and replaced by `v1`, `$color1` and `$color2` were never correctly
replaced and instead became `v11` and `v12` which caused a crash later
on.

- Never for global inputs
- Otherwise only if the temporary is referenced more than once
-> meaning it's actually caching the result of some operation
Tests updated accordingly.

Up until now, the QShaderGenerator would create temporary variables
for uniform, attributes, const. This change makes it use the global
inputs directly rather than relying on the intermediate properties.

GL2/ES2 expect it to be attribute and not in like later versions of OpenGL.

BuiltIn inputs shouldnt be translated into a code input. We comment the

I was mistaken before, the "es" part for that version isn't optional, it
*must* be omitted.
