[libclc] erfc: fix fp32 implementation in FTZ mode (#132390) 
On some implementations, the current implementation leads to slight
accuracy issues.

While the maths behind this implementation is correct, it does not take
into account the accumulation of errors coming from other operators that
do not provide correct rounding (like the exp function).

To avoid it, compute statically exp(-0.5625).

Fixes #124939
