target-arm: Implement new HLT trap for semihosting

Version 2.0 of the semihosting specification introduces new trap
instructions for AArch32: HLT 0xF000 for A32 and HLT 0x3C for T32.
Implement these (in the same way we implement the existing HLT
semihosting trap for A64).

The old traps via SVC and BKPT are unaffected.
