math_brute_force: only test correctly rounded divide/sqrt for fp32

Skip the correctly rounded divide (divide_cr) and sqrt (sqrt_cr)
tests for fp16 and fp64.

The corresponding build option to enable correctly rounded divide and
sqrt is named `-cl-fp32-correctly-rounded-divide-sqrt` and the
description refers only to "single precision floating-point", so this
option should not apply to fp16 or fp64.

The specification states that fp16 and fp64 divide and sqrt must be
correctly rounded for the full profile, without needing any additional
build options.  This is already tested by the regular divide and sqrt
tests.  For the embedded profile the ULP requirement is non-zero, but
there is no build option to request a correctly rounded implementation
anyway.

Fixes #1901 .
Relates to #1996 .
