[OTA Matter.framework] Missing helping functionality for OTA implementation.

[krypton36]

Problem

Matter framework contains a new feature that allows the ability to perform OTA SW. There is additional functionality that is missing in order for the consumer to properly implement OTA. The missing functionality is as follows:

• OTAImageHeader structure and OTAImageHeaderParser in OTAImageHeader.h needs to be exposed in Matter.framework
• MakeURI function in BdxUri.h needs to be exposed in Matter.framework.

Proposed Solution

• Add missing functionality to Matter.framework.
