target/arm: Restructure has_vfp_d32 test

One cannot test for feature aa32_simd_r32 without first
testing if AArch32 mode is supported at all.  This leads to

qemu-system-aarch64: ARM CPUs must have both VFP-D32 and Neon or neither

for Apple M1 cpus.

We already have a check for ARMv8-A never setting vfp-d32 true,
so restructure the code so that AArch64 avoids the test entirely.
