target-arm/arm-semi.c: Support widening APIs to 64 bits
The 64-bit A64 semihosting API has some pervasive changes from
the 32-bit version:
* all parameter blocks are arrays of 64-bit values, not 32-bit
* the semihosting call number is passed in W0
* the return value is a 64-bit value in X0
Implement the necessary handling for this widening.
