rp2: Increase micropython stack allocation

Browse Source 
We were running out of stack for micropython, and the core1 code doesn't
need 4k. So shift the allocation so that micropython has 6k and core1
has 2k. Adjust the linker script since it didn't support splitting
SCRATCH_X between the two stacks.
