[nrfconnect] Pulled patches for the nRF Wi-Fi platform (#33196)

* [nrfconnect] Adapt Matter SDK to the WiFi FW patch on external flash

This commit sets the default kconfigs if the WiFi FW patch on
external flash is enabled.

* [nrfconnect] Wi-FI directed scan implementation

This patch implements directed scanning and
single ssid scanning during commissioning.

* [nrfconnect] Fix build for 7001 Emulation

For nRF7001DK (emulation) build fails with SPI driver errors, this fixes
the build.
