This shares more code and calls the new shared load_tess_varyings()
abi so that the radeonsi nir path now supports tcs output loads.

The code to load outputs is essentially the same as load inputs
so we make the interface more generic to maximise code sharing.
We will make use of the new support in the following patch.

This is an optimisation that is recommended by Matt Arsenault,
and used by RadeonSI, but it's not compatible with Vulkan.
Note that AC_FLOAT_MODE_UNSAFE_FP_MATH includes the no signed
zeros flag in LLVM.

When that debug option is not used, we use the default float mode
because the no signed zeros optimisation is not Vulkan compatible.

This can't work for two reasons:
- TESSINNER/TESSOUTER are shader input values, so never translated
to the intrinsic ops
- the shader info pass scans the current stage but we want to know
in TCS, if TES reads the tess factors.
This fixes 6 regressions related to
deqp-vk/tessellation/shader_input_output/tess_level_{inner,outer}_XXX_tes
