tests: zephyr: ram_context_for_isr: Extend Zephyr test

Create the same test as for Zephyr in
nrf/tests/application_development directory and
disable KMU by default for all the NRF54L and NRF71 devices.

This test is incompatible with the KMU because it changes
the placement of the RAM in the linker files and this collides
with the KMU logic. But it also does not need the KMU so there
is no need to be there.

The KMU dependency to reserve the top RAM address is planned
to be done in dts (NCSDK-31980). Hopefully when this is done
this noup can be removed.

This commit replaces the following noup commits to sdk-zephyr:
1. e5618fec38e228854881ecc4ff9c993894a705d1
2. 206c0efa9be0b49e1ab7bffb09978da18368ba40
