Memory > Allocation Tracing: checkboxes are not clickable in profile mode

[polina-c]

For profile mode we need to show empty tab with message like 'Run application in debug mode to enable allocation tracing'.

We're getting a Compiler is disabled in AOT mode response to setTraceClassAllocation, but it's not clear why we need a compiler available to enable tracing here. I'm following up with @rmacnak-google to determine whether or not enabling tracing requires code to be generated at runtime.

This should be resolved. See https://github.com/flutter/devtools/pull/7058
