[iwl-next, v1] igc: Group frame size macros in igc_tsn.h

[iwl-next, v1] igc: Group frame size macros in igc_tsn.h

[Sasha Neftin]

Move the IGC_EMPTY_FRAME_SIZE definition from igc_main.c to igc_tsn.h.
This consolidates frame-size definitions for TSN and frame context
descriptors into a single header alongside IGC_RX_MIN_FRAG_SIZE and
SMD_FRAME_SIZE, making the constants available across TSN modules.
