pw_i2c: Add feature support to Initiator class

We allow the user to specify the supported features of their initiator
upon construction. All i2c messages are validated against this set of
features before transmission. If new features are added in the future,
the initiator-author will need to add them to the constructor to allow
that new feature's use.

The supported features are read, ten bit addressing, and write
continuations.

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/.
