* FuriHal: update STM32CubeWB to latest version. * Makefile: debug other script * FuriHal: correctly handle 0 size transfers in VCP * Dolphin: cleanup and minor timer tuning. * FuriHal: update FreeRTOS config with bigger timer command queue. * FuriHal: delayed irq enabling, fixes missing ticks. * FuriHal: use SFSA to determine free space for internal FS, update linker script to use as much space as theoretically possible. * Scripts: update core2 flashing scripts and OB data. * Github: bundle resources, core2 firmware and supplementary data. * GitHub: versioning for supplemental artifacts
