MLECO-3232: Add basic cmake presets

Assuming cmake 3.21 adds basic configuration and build presets:
* Target mps3 board with gcc
* Target mps3 board with armclang
* Target simple platform with gcc
* Target simple platform with armclang
* Target native build system
Adds test preset for native build to run default ctests.
Adds respective doc section to building instructions.

Note: hidden configurationPresets are to be moved to respective project
directories once cmake 3.24 is supported in the codebase and preset
include is supported.
Note: it is encouraged to create a personal CMakeUserPresets.json with
personal preferences like specific `LOG_LEVEL` and `jobs` for faster
compilation time.

Usage example:
cmake --preset=mps3-gcc

+### Building with CMakePresets
+
+If you are using CMake version 3.21 or above, then an alternative method of building is by using CMakePresets.
+This can be done by calling the following command:
+```commandline
+cmake --preset <platform>
+cmake --build --preset <platform>
+```
+where platform is one of:
+```commandline
+native
+mps3-gcc
+mps3-clang
+simple-gcc
+simple-clang
+```
+This will automatically configure and build the evaluation-kit into a corresponding folder.
+You can still pass in build flags as usual, for example:
+```commandline
+cmake --preset mps3-gcc -DUSE_CASE_BUILD=inference_runner
+cmake --build --preset mps3-gcc
+```
+Alternatively, you can create a CMakeUserPresets.json in the root of the project with personal user settings, for example:
+```commandline
+{
+  "version": 3,
+  "cmakeMinimumRequired": {
+    "major": 3,
+    "minor": 21,
+    "patch": 0
+  },
+  "configurePresets": [
+    {
+      "name": "my-config",
+      "displayName": "my-config",
+      "inherits": ["mps3-300-gcc"],
+      "cacheVariables": {
+        "LOG_LEVEL": {
+          "type": "STRING",
+          "value": "LOG_LEVEL_DEBUG"
+        }
+      }
+    }
+  ],
+  "buildPresets": [
+    {
+      "name": "mps3-300-gcc-custom",
+      "displayName": "mps-300-gcc-custom",
+      "configurePreset": "my-config",
+      "targets": [
+        "ethos-u-object_detection",
+        "ethos-u-inference_runner"],
+      "jobs": 12
+    }
+  ]
+}
+```
+
 ### Building the configured project
 
 If the CMake command succeeds, build the application as follows:
