hw/arm/stellaris: Split stellaris-gptm into its own file

Browse source 
The implementation of the Stellaris general purpose timer module
device stellaris-gptm is currently in the same source file as the
board model.  Split it out into its own source file in hw/timer.

Apart from the new file comment headers and the Kconfig and
meson.build changes, this is just code movement.
