subsys: console: Add pull-style console API support. This change introduces console_getchar() and console_getline() API calls which can be used to get pending console input (either one char or whole line), or block waiting for one. In this regard, they are similar to well-known ANSI C function getchar/gets/fgets, and are intended to ease porting of existing applications to Zephyr, and indeed, these functions (shaped as an external module) are already used by few applications. The implementation of the functions is structured as a new "console" subsystem. The intention is that further generic console code may be pulled there instead of being in drivers/console/. Besides the functions themselves, initialization code and sample applications are included. At this time, there're may limitations of how these functions can be used. For example, console_getchar() and console_getline() are mutually exclusive, and both are incompatible with callback (push-style) console API (and e.g. with console shell subsystem which uses this API). Again, the intention is to make a first step towards refactoring console subsystem to allow more flexible real-world usage, better reusability and composability.

subsys: console: Factor out fifo-based console input abstraction Console subsystem is intended to be a layer between console drivers and console clients, like e.g. shell. This change factors out code from shell which dealed with individial console drivers and moves it to console subsystem, under the name console_register_line_input(). To accommodate for this change, older console subsys Kconfig symbol is changed from CONFIG_CONSOLE_PULL to CONFIG_CONSOLE_SUBSYS (CONFIG_CONSOLE is already used by console drivers). This signifies that console subsystem is intended to deal with all of console aspects in Zephyr (existing and new), not just provide some "new" functionality on top of raw console drivers, like it initially started.
