wifi: rtw89: introduce fw feature group and redefine CRASH_TRIGGER

Some FW features may have variants on how to deal with in leaf functions,
e.g. H2C commands. However, from SW component point of view, it might not
matter which variant is supported exactly. In some cases, SW component may
just care whether any of the variants is supported or not.

So, introduce a concept of FW feature group which can manage a set of FW
features and can easily be checked if at least one of them is supported.

Since CRASH_TRIGGER will have variants and then matches the case mentioned
above, so redefine CRASH_TRIGGER as a FW feature group and add a variant
of type 0 for original handling.
