* shader: emit float min/max as host instructions on AMD GPUs
V_MIN_F32, V_MAX_F32, V_MIN3_F32 and V_MAX3_F32 were emulated with a
classify-and-select sequence of about a dozen instructions each, to give
the guest's NaN and signed-zero results on any host. AMD GPUs execute
GLSL.std.450 NMin/NMax with those same rules, so emit them directly when
the device is AMD and supports VK_KHR_shader_float_controls2. Each
instruction is decorated FPFastMathMode None, since
SignedZeroInfNanPreserve does not cover extended instructions. MED3 keeps
its exact emulation. KYTY_EMULATED_FLOAT_MIN_MAX=1 keeps the emulation.
In SAROS the two heaviest compute shaders get 37% and 59% faster on an
RX 9070 XT (RADV), about 4 ms of GPU time per frame.
Adds VectorMinMaxF32RuntimeEdges (runtime operands, so nothing is folded)
and a --float-min-max-only mode that runs it and
VectorMinMaxF32NanAndSignedZeroEdges with the emulation and, where
supported, with host instructions.
Developed with AI assistance (Claude Code).

* shader: gate host float min/max on RADV and check the emitted instructions
* shader: drop float controls 2 from host float min/max
* shader: drop the float min/max env override and atomic flag
* shader: pass host capabilities to the SPIR-V emitter as a profile built once per device
* shader: enable host float min/max on AMD GPUs
