pw_kvs: Remove unnecessary Key alias and test

pw_kvs originally used std::string_view for keys. A downstream project
wanted to use pw_kvs in C++14, so implemented pw::kvs::Key, a custom
version of std::string_view in e64daf43. That team later migrated to a
newer C++ standard, and Pigweed dropped C++14 support, so the Key
implementation was converted to an alias.

The Key alias is unused outside pw_kvs, so remove it. Also remove code
that hints at C++14 support, since it is not supported in Pigweed.

This is potentially a BREAKING CHANGE! References to pw::kvs::Key must
be replaced with std::string_view.

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/.
