[MEP] Platform initial support for eSim Multiple Enabled Profiles.

Port concept is introduced to support MEP feature. Refactoring UiccController, UiccCard, and
UiccProfile to add UiccPort between UiccCard and UiccProfile. Most of the UiccCard functioning is
moved to UiccPort.

Added default port index value of uicc card.
