[FL-3579, FL-3601, FL-3714] JavaScript runner (#3286)

* FBT: cdefines to env, libs order * API: strtod, modf, itoa, calloc * Apps: elk js * Apps: mjs * JS: scripts as assets * mjs: composite resolver * mjs: stack trace * ELK JS example removed * MJS thread, MJS lib modified to support script interruption * JS console UI * Module system, BadUSB bindings rework * JS notifications, simple dialog, BadUSB demo * Custom dialogs, dialog demo * MJS as system library, some dirty hacks to make it compile * Plugin-based js modules * js_uart(BadUART) module * js_uart: support for byte array arguments * Script icon and various fixes * File browser: multiple extensions filter, running js scripts from app loader * Running js scripts from archive browser * JS Runner as system app * Example scripts moved to /ext/apps/Scripts * JS bytecode listing generation * MJS builtin printf cleanup * JS examples cleanup * mbedtls version fix * Unused lib cleanup * Making PVS happy & TODOs cleanup * TODOs cleanup #2 * MJS: initial typed arrays support * JS: fix mem leak in uart destructor Co-authored-by: SG <who.just.the.doctor@gmail.com> Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
