  [compiler-rt][AArch64] NFCI: Simplify __arm_get_current_vg. (#119210)

This patch simplifies the code in two different ways:
* When SVE is available, return `cntd` directly to avoid the need for
bitfield insert.
* When SME is available, check the PSTATE.SM bit of `SVCR` directly
rather than calling `__arm_sme_state`.
