target/sh4: Fix TB_FLAG_UNALIGN
The value previously chosen overlaps GUSA_MASK.
Rename all DELAY_SLOT_* and GUSA_* defines to emphasize
that they are included in TB_FLAGs. Add aliases for the
FPSCR and SR bits that are included in TB_FLAGS, so that
we don't accidentally reassign those bits.
Fixes: 4da06fb3062 ("target/sh4: Implement prctl_unalign_sigbus")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/856
