py/asmarm: Fix halfword loads with larger offsets.
This commit fixes code generation for loading halfwords using an offset
greater than 255.
The old code blindly encoded the offset into a `LDRH Rd, [Rn, #imm]`
opcode, but only the lowest 8 bits would be put into the opcode itself.
This commit instead generates a two-opcodes sequence, a constant load into
R8, and then `LDRH Rd, [Rn, R8]`.
This fixes `tests/extmod/vfs_rom.py` for the qemu/SABRELITE board.
