Some optimizations for the hardware divider (#1033) 
* Remove unnecessary wait in pico_divider.

There is no need to wait if there is more than 8 cycles between setup and result readout.
Dividend/divisor readout should be correct without delay. Update comment to reflect that.

* Optimize hw_divider_save_state/hw_divider_restore_state.

Doing multiple pushes to avoid stack usage is faster.
The wait loop in hw_divider_save_state had an incorrect branch in the wait loop.
This didn't matter since the wait wasn't necessary to begin with.

* Remove pointless aligns in hardware_divider.

The regular_func_with_section inserts a new section so if aligning
is desired it should be placed in the macro after section start.

* Save a few bytes in hardware_divider.

Signed and unsigned code can use the same exit code.
Branching to the common code is free since we need the 8 cycle
delay anyway.

Implement whole-buffer write semihosting (#1013) 
* Implement whole-buffer write semihosting

Each semihosting call is very slow, so doing it for each character
does not provide an ideal developer experience.

This change allows the entire buffer to be printed out in a single call.
