refactor: introduce @bitwarden/state and other common libs (#15772)

* refactor: introduce @bitwarden/serialization

* refactor: introduce @bitwarden/guid

* refactor: introduce @bitwaren/client-type

* refactor: introduce @bitwarden/core-test-utils

* refactor: introduce @bitwarden/state and @bitwarden/state-test-utils

Creates initial project structure for centralized application state management. Part of modularization effort to extract state code from common.

* Added state provider documentation to README.

* Changed callouts to Github format.

* Fixed linting on file name.

* Forced git to accept rename
