tests: drivers: sdhc: add test for card insertion interrupt

Browse source 
Add test for card insertion interrupt to SDHC test.

The test will now wait for the card insertion interrupt whenever it is
run without a card in the slot. By inserting a card, the user can verify
that card insertion interrupts work correctly, as this should notify the
test and allow it to proceed.
