pw_checksum: Add additional CRC32 variants

CRC32 implementations make size/performance tradeoffs.  The current
eight bits per iteration, 256 entry table implementations balances
heavily towards increasing size for better performance.  This patch
adds two additional implmentations that make different tradeoffs.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
