  [XRay] xray_fn_idx: fix alignment directive

Use `emitValueToAlignment` as the section does not contain code.
`emitCodeAlignment` would lead to ALIGN relocations on RISC-V and
LoongArch with linker relaxation.

In addition, change the alignment to wordsize, sufficient for the
runtime requirement (`XRayFunctionSledIndex`).
