[nxp][examples][common] Make button components configurable (#36077)

Introduce the following flags: - CONFIG_APP_BUTTON_ENABLED - flag to configure if ButtonApp instance is registered. - CONFIG_BLE_BUTTON_ENABLED - flag to configure if ButtonBle instance is registered. - CONFIG_APP_BUTTON_HANDLE_SDK_PREDEFINED - flag to configure if the button handle is predefined in the SDK or not. If not set, the handle will be defined and initialized explicitly in the file. Signed-off-by: marius-alex-tache <[email protected]>
