[Offload][Conformance] Add exhaustive tests for half-precision math functions (#155112)
This patch adds a set of exhaustive tests for half-precision math.

The functions included in this set were selected based on the following
criteria:
- An implementation exists in `libc/src/math/generic` (i.e., it is not
just a wrapper around a compiler built-in).
- The corresponding LLVM CPU libm implementation is correctly rounded.
- The function is listed in Table 69 of the OpenCL C Specification
v3.0.19.

This patch also fixes the testing range of the following functions:
`acos`, `acosf`, `asin`, `asinf`, and `log1p`.
