enable long interleaving mode for LR11x0 and SX128x (#9399)

Browse Source 
Using long interleaving is not a breaking change, the receiver node is able
to use the lora header to know if LI encoding is used or not and will
decode LI packets correctly.

However the problem is SX127x and other first generation LoRa IP which do not
support LI at all, for theses it is a breaking change.

HOWEVER due to the sync word bug the LR11x0 already can't talk with SX127x,
so if we enable LI on theses no one would be able to tell.
Same for SX128x altho this is because it works on 2.4Ghz which is incompatible with SX127x.
