Add CPU cycle counter accessors (#226) ...

Use the 24-bit SYSTICK peripheral, wrapped in logic to extend it to a
full 32 or 64bits.  W/o the wrapper, SYSTICK will wrap around in ~100ms.

Adds rp2040.getCycleCount() and rp2040.getCycleCount64()

Clean up the libpico build process as crt0.S from the pico-sdk should
be directly used.

Clean up the keywords file.
