The new GRTC reading manner of the SYSCOUNTER uses hardware mechanism which
allows to keep it alive when any of CPUs is not sleeping. Otherwise
the SYSCOUNTER goes into sleep mode. Thus there is no
longer need to maintain the `CONFIG_NRF_GRTC_SLEEP_ALLOWED` symbol, however
if the user wants to have the SYSCOUNTER enabled all the time the
`CONFIG_NRF_GRTC_ALWAYS_ON` can be used instead.
The nrfx_grtc driver no longer provides the `wakeup-read-sleep` reading
manner.
Also setting the GRTC clock source is performed by the nrfx_grtc driver so
it has been removed from the `sys_clock_driver_init()` function.

GRTC needs to use direct clock source path instead of system clock path
to support ELV mode for nRF54L targets.

Currently function `z_nrf_grtc_wakeup_prepare()` should be available
only for the GRTC manager (`CONFIG_NRF_GRTC_START_SYSCOUNTER` is active).

This commit aligns the GRTC driver to changes introduced in
hal_nordic. Some of the features regarding GRTC sleep/wakeup
functionality has been modified and moved out to the nrfx
driver's code.

d599e2b670 removed early return from sys_clock_timeout_handler if
current counter value is less than cc_val. It seems that this return is
needed as after the removal some stress tests which were using system
timers heavily started to hang.

Misc fixes for the grtc timer driver:
* In non tickless mode:
* The tick time would drift a bit with each interrupt
* If something would cause a very significant delay
in handling the tick interrupt the number of announcements
would be incorrect
* Fortickless mode: The calculation of the next tick time
in sys_clock_set_timeout() was incorrectly done,
resulting in two spurious, too early, wakes of the kernel
before each correct wake. This caused tests/kernel/context/
to fail.

Negative error codes cannot be returned if the function returns an
unsigned integer. Change function's API to return the read compare
register value through a pointer and the actual result as a signed
integer.

Interrupt handlers are expected to have a pototype
void (const void*)
but nrfx_grtc_irq_handler has just a void(void)
(with no input parameter).
Fix it by using a trampoline.

Include into compilation the nrfx_gppi_dppi_ppib helper and related
interconnect layers when DPPIC nodes are enabled in DTS. Provide macro
definitions required by those interconnect layers based on information
from devicetree (the nrf_grtc_timer is only modified because a macro
that it uses became more generic).

Move code that prepares `NRFX_CONFIG_GRTC_*` definitions based on
information from devicetree from the nRF54L15 nrfx_config header
to the global one, so that the code can be used by nRF54H20, too.
The checks that validate owned-channels and child-owned-channels
DT properties are moved to the nrf_grtc_timer driver so that
the global nrfx_config is not polluted unnecessarily.
The default values in nrfx_config_nrf54l15_enga_application.h
are restored to those from the corresponding template file.
