We move the SYS_CACHE_SHIFT_N options from arch/arm/Kconfig to arch/Kconfig, and introduce SYS_CACHE_SHIFT_4 to provide a size of 16. Introduce select statements for other architectures based on current usage. For MIPS, we take the existing arch-specific symbol and migrate to the generic symbol. This lets us remove a little bit of otherwise unused code.

I'm Cc'ing a bunch of RISC-V folks since that's where I'm least confident and just put it per-board for now.
