radv: lower 64-bit drcp/dsqrt/drsq for fixing precision issues
The hardware precision of v_rcp_f64, v_sqrt_f64 and v_rsq_f64
is less than what Vulkan requires.
This lowers using the Goldschmidt's algorithm to improve precision.
Fixes dEQP-VK.glsl.builtin.precision_double.* on both compiler
backends.
