anv: remove shader fp64 inspection after parsing

Browse source 
Unfortunately some crucible tests are using all floating point widths
in a single shader and specializing a variable to select what code
path to use for a particular supported floating point width. This is
reporting errors in the validation layers.

Remove the validation for now.
