McpService: Allow to read MCP service by devices supporting LeAudio

Current authorication mechanism is done in the way, that remote device
needs to have connected LeAudio service in order to be authorize to
operate on MCP.

This might cause issue, when LeAudio service connects after remote
device tries to read MCP service.

This patch, looks into supported services by remote device, and if
LeAudio is supported, authorization is granded.
