tests/hlsl: Use explicit infinities in cast-to-half.shader_test.

Browse Source 
We used to need workarounds when we used scanf() to parse float
numbers, but now we use strtof() which supports "inf" properly.
On the other hand, on some platforms it is the workaround that
now fails with a range error.
