Added Warning in ML Timeline plugin if no microcontroller section in aie trace metadata

Added a warning message for AIESW-25043 fix
aiecompiler should always generate microcontroller section in AIE trace metadata.

MLTimeline already has default handling if required uC metadata is not available. Disabling ML Timeline due to missing metadata will break tests with missing metadata but working till now using default handling.
Lets discuss this offline.

Hi @garimadhaked Please avoid disabling ML Timeline feature for missing Microcontroller info. On NPU3, we add default uC info as index 0 column 0 in the ML Timeline Plugin so that it configures the debug buffer for 1 controller.

XDP/profile/plugin/ml_timeline/clientDev/ml_timeline.cpp

Line 83 in 8eb1120

if (activeUCs.empty()) {

So on NPU3, we dont hit the debug buffer configuration with 0 byte size issue. So, no change is required for NPU3 version.
For VE2, repo has handling for missing AIE_TRACE_METADTATA but not missing uC info if AIE_TRACE_METADATA is found. Please add fallback to buffer sectioned per column for empty "activeUCs", instead of disabling ML Timeline feature.
