Make per-target shader baking reproducible

In per-target compilation mode bake() generates a separate SPIR-V binary
for each requested target, and then has to pick one of them to generate
the single QShaderDescription of the resulting QShader from. That pick
was the first element of a QHash, and so depended on the per-process
randomized QHash seed: invoking qsb twice with the very same arguments
could produce .qsb files that differ in their reflection info. That in
turn defeats reproducible builds and content-addressed build caches.

Use ordered maps instead. As a bonus this makes the choice a sensible
one, not merely a stable one: QShader::SpirvShader is the first Source
enum value, hence the reflection info now always comes from the plain
SPIR-V target whenever one was requested (which qsb always does).

Note that when a shader declares its resources differently depending on
the QSHADER_SPIRV/GLSL/HLSL/MSL macros, the reflection info can only
ever be correct for one of the targets. Nothing to do about that, given
that a QShader has one QShaderDescription, but at least the result is
now consistent between runs.

qsb: Keep the native-shader-info data when storing Metal bytecode

replaceShaderContents() moves the native resource binding map and the
separate-to-combined image sampler mapping table from the original key
to the new one, but not the native shader info. The MSL-specific data
was therefore lost whenever -t/--metallib replaced the MslShader entry
with a MetalLibShader one.

That data is not optional: the Metal backend looks up the extra buffer
bindings for tessellation and for the buffer size buffer, and asserts on
their presence.

Doc: Rename the second qt_add_shaders argument to resource_name

The synopsis called it <name>, which doesn't say what the value is
used for. It is the name of the generated resource, same as for
qt_add_resources().
