laura hermanns 1d344a72de [UBA] Add breadcrumbs to UBA trace files. ...

This change adds a new field to the ProcessStartInfo struct in UBA trace files for a description of the task, called "breadcrumbs" which allow to diagnose and backtrace the origin of a UBA task.
This is also hooked up to the distributed shader compilation (added as new field in FTaskCommandData) and a descriptive string is generated for each shader compile job batch.
UbaVisualizer is updated accordingly to integrate this new data when hovering over a task in the timeline.
This feature can be enabled via the new CVar "r.ShaderCompiler.DistributedJobDescriptionLevel" with values 0 (Disabled), 1 (Basic information), 2 (Adds shader format to each job). It's disabled by default.
