  Log Message:
  -----------
  [libclc] Use float sw_fma for spirv*-mesa-mesa3d targets (#199626)

This partially reverts 39f3d72b72fd, which changes almost all targets to
use __builtin_elementwise_fma.
The same revert was done for clspv in 1d719edd9935.

Restore __clc_runtime_has_hw_fma32 so that Mesa can dynamically change
its behavior to enable native fma for specific hardware.

Fixes #198542
