target-arm: Implement ARMv8 single-stepping for AArch32 code

ARMv8 single-stepping requires the exception level that controls
the single-stepping to be in AArch64 execution state, but the
code being stepped may be in AArch64 or AArch32. Implement the
necessary support code for single-stepping AArch32 code.
