Michael Pratt 876d477b0e runtime: refactor ARM VDSO call setup to helper 
We have a very complex process to make VDSO calls on ARM. Create a
wrapper helper function which reduces duplication and allows for
additional calls from other packages.

vdsoCall has a few differences from the original code in
walltime/nanotime:

* It does not use R0-R3, as they are passed through as arguments to fn.
* It does not save g if g.m.gsignal.stack.lo is zero. This may occur if
it called at startup on g0 between assigning g0.m.gsignal and setting
its stack.

For #49182
