pw_toolchain: Introduce RuntimeInitGlobal

- Introduce RuntimeInitGlobal, a wrapper for global variables that
  should never be constant initialized.
- Update NoDestructor to allow constant initialization. If constant
  initialization is not desirable, use RuntimeInitGlobal.
- Add a section to the docs describing the benefits and pitfalls of
  constant initialzation.
- Enable layering_check for pw_toolchain.

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/.
