[FL-3846] Event Loop Timers (#3721)
* Implement POC event loop tmers (not all edge cases are handled)
* Use a separate ready list to allow for (re)starting and stopping of timers from callback
* Improve the test application
* Improve timer API and test application
* Improve timeout calculation logic
* Improve timer API, update documentation
* Fix API usage error
* Update doxygen comments
* Revert the old (correct) check
* Improve function naming
* Check whether a timer was on the expired list before processing it
* Implement tick callback
* Add critical sections to improve timer consistency
* Simplify event loop timer API
* Remove redundant search
* Refactor timer logic, use message queue
* Simplify FuriEventLoopTimer API
* Improve event loop timer logic
* Update the f18 target
* Remove superfluous clears
* Correct f18 api symbols
* Fix doxygen comments
* Update .pvsconfig
* Use a double push list instead of deque
* Update .pvsconfig
* Add pending callback functionality
* Restore unprocessed flags when applicable
* Refactor Dolphin app to use FuriEventLoop
* Improve naming
* Update naming some more
* Fix a typo Co-authored-by: Silent <CookiePLMonster@users.noreply.github.com>
* Fix wait time in example
* Bump API version
* Debug: multiple of 25 timings in event loop blink test
* Separate FuriEventLoopTimer to its own set of files
* Improve start time calculation for periodic timers
* Do not use dynamic allocations for timer requests
* Split the tick functionality in separate files, rearrange code
* Improve timer queue handling
* Properly reset GPIO pins in the test app
* Properly initialise GPIO pins in the test app too
* Furi: variable naming in event loop
* Furi: fix spelling in event loop
