[FL-2527] Updater: Migrating to new manifest path convention (#1213)

* Updater: Migrating to new manifest path convention
* RPC: Added update preparation status to RPC
* RPC: bumped protobuf submodule
* Bumped protobuf_version.h
* FuriCore: add missing include. Lib: make mlib smaller
* Explicitly tell where we have doubles and fix random in animations
* makefile: added -DLFS_NO_DEBUG
* Updater: path len constant dedup
* Updater: checking for hardware version match before parsing manifest
* LD: moved _DRIVER_CONTEXT sections to .bss, where they belong.
* LD: avoiding PROBGITS warning, moved _CONTEXT to data
* Updater: Added version check on update package - refusing to install outdated
