LOG: Fix type mismatch in ARM calling convention ternary (#180872)

GCC's -Wextra flags the ternary in the ARM half-precision calling
convention setup because the branches have different types. Use
static_cast to make both sides consistent.

Built with ToT clang and GCC 13.3.0 on Linux x86_64. All existing tests
pass.
