Ps/pm 2910/add browser storage services (#6849)

* Allow for update logic in state update callbacks

* Prefer reading updates to sending in stream

* Inform state providers when they must deserialize

* Update DefaultGlobalState to act more like DefaultUserState

* Fully Implement AbstractStorageService

* Add KeyDefinitionOptions

* Address PR feedback

* Prefer testing interactions for ports

* Synced memory storage for browser

* Fix port handling

* Do not stringify port message data

* Use messaging storage

* Initialize new foreground memory storage services

This will need to be rethought for short-lived background pages, but for
now the background is the source of truth for memory storage

* Use global state for account service

* Use BrowserApi listener to avoid safari memory leaks

* Fix build errors: debugging and missed impls

* Prefer bound arrow functions

* JSON Stringify Messages

* Prefer `useClass`

* Use noop services

* extract storage observable to new interface

This also reverts changes for the existing services to use
foreground/background services. Those are now used only in state
providers

* Fix web DI

* Prefer initializing observable in constructor

* Do not use jsonify as equality operator

* Remove port listener to avoid memory leaks

* Fix logic and type issues
