WIP ESP32 IDF port. Currently the UART driver break boot (or at least output).

Add ESP32C3 support/coexistence. The uzlib and parts of Lua had to be switched over to use the C standard int types, as their custom typedefs conflicted with RISC-V toolchain provided typedefs. UART console driver updated to do less direct register meddling and use the IDF uart driver interface for setup. Still using our own ISR rather than the default driver ISR. Down the line we might want to investigate whether the IDF ISR would be a better fit. Lua C modules have been split into common and ESP32/ESP32-S specific ones. In the future there might also be ESP32-C3 specific modules, which would go into components/modules-esp32c3 at that point. Our old automatic fixup of flash size has been discarded as it interferes with the checksumming done by the ROM loader and results in unbootable systems. The IDF has already taken on this work via the ESPTOOL_FLASHSIZE_DETECT option, which handles this situation properly.
