rS338208: if_media: Add new 2.5G/5G/25G/40G/50G/100G/200G/400G media types

Summary

The driver to support upcoming hardware from Intel supports more media types than what are in the kernel already, so this commit adds the missing media types.

These mostly include new 25/50/100G media types, as well as some for the brand new 200G/400G speeds.

In terms of adding new entries this looks fine. I don't know the media types to validate the entries themselves.

I see IFM_40G_ER4 is missing from the table. There is only IFM_40G_LR4 currently.

Can you add IFM_40G_ER4 as part of this patch aswell?

sys/net/if_media.h
503 ↗	(On Diff #46991)	Small typo: Gbase -> GBase

Fix typo (from @hselasky)

However, I now notice that all of the new media types use "Base" instead of "base". Should
they all be changed to use one or the other? Or should the "new/IFM_X()" types continue
to use "Base"?

I think "GBase" was the common before this change aswell.
