EHT: Add Multi-Link element field definitions

Define the following fields described in IEEE P802.11be/D2.1:
- Multi-Link element types as defined in Table 9-401c (Type subfield
  encoding)
- Basic Multi-Link element presence bitmap as defined in Figure
  9-1002g (Presence Bitmap subfield of the Basic Multi-Link element
  format)
