Added path for receiving data on SPI (SINGLE mode only, there will be another PR for QUAD).
For now, data is transceived byte by byte, and receiving starts right after transmission. This has its disadvantages, for example:

• INB register needs to be read when the transmission is still ongoing, otherwise, the clock will not be generated when a peripheral device is sending data (not sure why)
• Because data is transceived in bytes, there is less time between writing to OUTB and reading from INB. Although I checked that the current solution works for higher frequencies, it can still be a problem when processing a lot of requests from the APP.

There will be another ticket for fixing the above issues. Right now I am adding this so that we would have at least some working solution, even if it's not ideal.

Requires changes from #20114 to be able to receive data from nRF54L15 DK external flash.

@nordicjm I applied your suggestions. I also moved changes to snippets to another PR (#20114), since they are not needed for RX implementation, only for checking it.

[mif1-nordic]

Please rebase on #19877 as it will be merged first

[magp-nordic]

PR rebased after #19877 was merged, @masz-nordic @mif1-nordic , please, review again.
