igc: use FIELD_PREP and GENMASK for existing TX packet buffer size

In preparation for an upcoming patch that will modify the TX buffer size
in  TSN mode, replace IGC_TXPBSIZE_TSN and IGC_TXPBSIZE_DEFAULT
implementation with new macros that utilizes FIELD_PREP and GENMASK for
clarity.

The newly introduced macros follow the naming from the i226 SW User Manual
for easy reference.

I've tested IGC_TXPBSIZE_TSN and IGC_TXPBSIZE_DEFAULT before and after the
refactoring, and their values remain unchanged.
