Enable HAS_VFP_D32 for 32-bit armv8 crasher

Android.bp assumed only an armv7-a-neon core needs to set HAS_VFP_D32.
In fact, an armv8 core also has 32 double-word floating point registers
for A32 and T32 ISAs (AArch32 or 32-bit armv8).

Bug: 65568426
Test: lunch aosp_arm64; emulator # on oc-mr1-dev; boot to home screen.
      Check crashglue.o actually uses VFP_D16-31 for 32-bit armv8 core.
