  1. snippets: Add new snippet to enable build BLE samples with BT rpc_host 

    There is experimental RPC wrapper for Bluetooth API.
To make possible use of BLE samples with nRF54h20 and the RPC API
there is required a settings partition for Radio core.
That means current memory map has to be changed to make room for new
settings partition.
To make an application to use the Bluetooth rpc subsystem there is
added CONFIG_BT_RPC_STACK. It enables BT RPC host client wrapper to be
used instead of regular Bluetooth API.

With these changes end user needs to add -S nrf-bt-rpc to west call
to build a compatible BLE sample for BT RPC host.

To make clean complete build for both Radio and App cores addtitional
changes are required in sysbuild configuration. These will be added
in follow up commits.

The snippet can be also used for builds for nRF5340, though there is
no need for memory map reorganization.

  2. sysbuild: Add missing config that allows to build rpc_host for Rad core 

    There were no simple way to use sysbuild for building BLE samples
with rpc_host running on Radio core. Add required configuration to
sysbuild. Now an application can be targeted to be build with
rpc_host by adding NRF_DEFAULT_RPC_HOST=y to Kconfig.sysbuild.

  3. samples: bluetooth: peripheral_urat: Add nrf54h20 rpc_host to build 

    Add possibility to build the sample application targeted to nrf54h20
with use of Bluetooth API wrapped with RPC Host client. The Radio
core application in such case must be ipc_radio with enabled Bluetooth
RPC host. That reqires change to sysbuild configuration of the
sample application.

One note, the Bluetooth RPC subsystem requires to have same Bluetooth
device name on obth ends of RPC communication, so there is used
FILE_SUFFIX=bt_rpc and provided sysbuild configuration files that
are include when the suffix is used in build call.

To build the sample with enabled Bluetooth RPC subsys use:
'west build -b nrf54h20dk/nrf54h20/cpuapp --sysbuild -p
 -S nordic-bt-rpc -- -DFILE_SUFFIX=bt_rpc'

  4. Bluetooth: rpc: Change handling of remote settings initialization 

    The former implementation of settings initialization was based on
a command send by client by rpc_settings_set() function. That function
was called by stetings subsustem during settings_load() execution.
That together created deep execution call stack that required extended
main thread stack size.

To avoid the change to stack size, the implementation is changed,
to send the settings load command to host if CONFIG_SETTINGS is
eanbled. The command is send directly from bt_enable() function
in bt_rpc_gap_client.c.
