XER2-RDKB-65709: Enable ccsp-lm-lite support for the XER2 platform

[RAMANJULASREEHARI]

Reason for change: ccsp-lm-lite support for XER2

Test Procedure: Build should work
Priority:P1
Risks:Low

[Copilot]

Pull request overview

Enables ccsp-lm-lite support for the XER2 platform by adjusting how the RBUS handle is referenced in WAN traffic utilities (likely to satisfy platform-specific build/link requirements).

Changes:

• Changes rbus_handle from an extern declaration to a global definition in cosa_wantraffic_utils.c for _SR300_PRODUCT_REQ_ / _RDKB_GLOBAL_PRODUCT_REQ_ builds.

• Defining rbus_handle here introduces a second global definition under _SR300_PRODUCT_REQ_/_RDKB_GLOBAL_PRODUCT_REQ_. webpa_interface.c already defines a global rbus_handle in the same macro combination (when WAN_FAILOVER_SUPPORTED is enabled), which can cause multiple-definition linker errors. Even when it links, this file's rbus_handle is never initialized (no assignment found), so GetCurrentActiveInterface() may call rbus_get() with a NULL/unopened handle.

Prefer avoiding a shared global here: either keep this as an extern declaration and ensure there is exactly one definition, or switch GetCurrentActiveInterface() to use get_rbus_handle() from lm_rbus_api (or pass the handle in) so it doesn’t depend on another TU’s global.
