Instead of putting tinygo_scanCurrentStack in scheduler_*.S files, put
them in dedicated files. The function tinygo_scanCurrentStack has
nothing to do with scheduling and so doesn't belong there. Additionally,
while scheduling code is made specific for the Cortex-M, the
tinygo_scanCurrentStack is generic to all ARM targets so this move
removes some duplication there.
Specifically:
* tinygo_scanCurrentStack is moved out of scheduler_cortexm.S as it
isn't really part of the scheduler. It is now gc_arm.S.
* Same for the AVR target.
* Same for the RISCV target.
* scheduler_gba.S is removed, using gc_arm.S instead as it only
contains tinygo_scanCurrentStack.
