* First part of multitarget porting * Delete firmware/targets/f7/Inc directory * Delete firmware/targets/f7/Src directory * gpio: cli fixes; about: using version from HAL * sdk: path fixes * gui: include fixes * applications: more include fixes * gpio: ported to new apis * hal: introduced furi_hal_target_hw.h; libs: added one_wire * hal: f18 target * github: also build f18 by default * typo fix * fbt: removed extra checks on app list * api: explicitly bundling select mlib headers with sdk * hal: f18: changed INPUT_DEBOUNCE_TICKS to match f7 * cleaned up commented out code * docs: added info on hw targets * docs: targets: formatting fixes * f18: fixed link error * f18: fixed API version to match f7 * docs: hardware: minor wording fixes * faploader: added fw target check * docs: typo fixes * github: not building komi target by default * fbt: support for `targets` field for built-in apps * github: reworked build flow to exclude app_set; fbt: removed komi-specific appset; added additional target buildset check * github: fixed build; nfc: fixed pvs warnings * attempt to fix target id * f7, f18: removed certain HAL function from public API * apps: debug: enabled bt_debug_app for f18 * Targets: backport input pins configuration routine from F7 to F18 Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
