[FL-3055] Getter for application data path (#2181)
* Threads: application id
* Unit tests: appsdata getter test
* Unit tests: moar test cases for appsdata getter
* Unit tests: remove folders after test
* Storage: dir_is_exist, migrate, + unit_tests
* Plugins: migration
* Storage: common_exists, moar unit_tests 4 "common_migrate", "common_migrate" and "common_merge" bugfixes
* Storage: use FuriString for path handling
* Storage API: send caller thread id with path
* Storage: remove StorageType field in storage file list
* Storage: simplify processing
* Storage API: send caller thread id with path everywhere
* Storage: /app alias, unit tests and path creation
* Storage, path helper: remove unused
* Examples: app data example
* App plugins: use new VFS path
* Storage: file_info_is_dir
* Services: handle alias if the service accepts a path.
* App plugins: fixes
* Make PVS happy
* Storage: fix storage_merge_recursive
* Storage: rename process_aliases to resolve_path. Rename APPS_DATA to APP_DATA.
* Apps: use predefined macro instead of raw paths. Example Apps Data: README fixes.
* Storage: rename storage_common_resolve_path to storage_common_resolve_path_and_ensure_app_directory
* Api: fix version
* Storage: rename alias message
* Storage: do not create app folders in path resolving process in certain cases.
