features/wifi: Add WiFi driver fragments for various vendors/interfaces
This change adds WiFi driver configuration fragments. The fragments are
split into vendor and interface files to allow for easy selection of
drivers for specific interface types (USB, PCI, SDIO) which is useful
for BSPs with specific interfaces. The specific vendor/interface config
fragments can be included by specific BSPs in its .scc files.
However .scc files (wifi-*.scc) are provided to allow enabling interface
specific or all interfaces drivers via KERNEL_FEATURES or inclusion via
other .scc files. And wifi-common.scc is provided to enable the base
config options required for all WiFi drivers, which is done to ensure
correct configuration for default no config setups (e.g.
linux-yocto-tiny).
This patch only enables a limited set of drivers, which is based on what
the common-pc-wifi.cfg fragment sets as well as some additional drivers,
that primarily appear in USB WiFi devices.

This gives us a much better granularity of drivers and a good baseline for
future improvements.
The 4.12 fragments are also slightly re-organized on top of this commit
to avoid patch failures when including the new frags.
