Remove lib_deps section for all PlatformIO envs which are unneeded (only references the `extends` lib_deps, thus pointless)
This makes the configs more concise and make future PIO variants/ libdeps audits easier.
Also move RAK3172 and new EBYTE_E77_MBL define to variant.h, as this makes VSCode know about the defines properly...
