[NativeAOT/ARM] Emit correct unwind codes for VPOP

[filipnavara]

Tested on JIT tests

Unwind codes:

0x1c70 <MathCeilingSingle_ro_MathCeilingSingleTest_Program__TestEntryPoint>: @0x428
  Compact model index: 1
  0x01      vsp = vsp + 8
  0xc9 0x81 pop {D8-D9}
  0x84 0x8f pop {r4, r5, r6, r7, r11, r14}
  0xb0      finish

0x37370 <System.Globalization.CalendricalCalculationsHelper__EquationOfTime>: @0x9f54
  Compact model index: 1
  0x09      vsp = vsp + 40
  0xc9 0x86 pop {D8-D14}
  0x84 0x80 pop {r11, r14}
  0xb0      finish
