Mark more Plan B only functions with PLAN_B_ONLY macro.

This CL marks various functions and methods that are only relevant for
Plan B SDP semantics with the PLAN_B_ONLY macro. This is part of the
ongoing effort to deprecate and eventually remove Plan B support.

Changes include:
- Marking methods in MediaDescriptionOptions, RtpTransceiver, and RtpTransmissionManager.
- Adding suppression macros (RTC_ALLOW_PLAN_B_DEPRECATION_BEGIN/END) to existing call sites in SdpOfferAnswerHandler and test utilities.
- Adding comments to constructors where PLAN_B_ONLY couldn't be used due to templating issues (e.g., when used with make_ref_counted).
- Removing suppression macros from functions that are already marked
as PLAN_B_ONLY

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
