samples: wifi: radio_test: Add a single domain combo radio test

With the introduction of 54L15 SoC where the complete BLE stack runs on
the CPUAPP itself, reorg the radio test directories based on domains.
Single domain radio test is primarily for 54L15 (and other similar
SoCs) which basically combines Wi-Fi and Peripheral radio test samples
in to one.

+Wi-Fi BLE Radio Test Sample
+###########################
+
+The Wi-Fi BLE Radio Test sample demonstrates how to use the radio test for both Wi-Fi and BLE protocols using a single domain image i.e., both running on the same core.
+The sample demonstrates how to use the radio test subcommands to configure the radio test parameters and run the radio test.
+
+The Wi-Fi Radio test also supports programming the Factory Information Configuration Registers (FICR) fields defined in the nRF7002 one-time programmable (OTP) memory.
+
+See the subpages for detailed documentation on the sample and its features.
