pw_span: Remove pw_polyfill dependency

This dependency was added back when the type needed to support more
limited constexpr semantics for C++11 and/or C++14. Those language
versions are no longer targeted, and so the header is now just hanging
around as a ghost.

Note that compatibility_test.cc still depends on pw_polyfill. As a
result, I've added the relevant dependency for the module that builds
that test.

Also, pw_varint/varint.h was naughty and depended on pw_polyfill
transitively through pw_span, so I also have had to fix it.

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/.
