To save resources, some devices where LR11x0 was never an option
excluded it from compilation, using RADIOLIB_EXCLUDE_LR11X0 .
As we will soon have LR2021 support, apply the same treatment
to that chip to these devices, by adding RADIOLIB_EXCLUDE_LR2021
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.
