### Features
This change sets up new interface APIs and moves concrete APIs into those interfaces to allow for providers to be implemented external to TraceServices. These Provider interfaces are given to new construction APIs in ExternalAnalysis.h that construct the appropriate Analyzer with the specified Providers.
This change creates a new and standalone Analyzer for Bookmarks spinning logic directly out of the MiscAnalyzer. This is necessary to prevent bookmark processing necessitating additional Providers that the client may not want to implement if they just want access to Bookmark data.
SummarizeTraceCommandlet implements these provider interfaces and migrates it's state tracking implementation from raw event decoding to simply forwarding on the calls from the Provider interfaces. The internal SummarizeTraceCommandlet Analyzer API in the Commandlet are mostly left unchanged as a middleman between Trace and the Commandlet existed prior to this change.
### Implementation
Since Providers can now implement multiple interfaces, we need to upcast them to the appropriate interface at registration time. This in turn requires moving the Provider memory model into IAnalysisSession to TSharedPtr/MakeShared to prevent double deletes at destruction time.
### Performance
Opening a large trace in Insights yields this performance change:
Pre: Analyzed in 8.29s at 122.8X speed.
Post: Analyzed in 8.36s at 121.8X speed.
Commandlet runtime is comparable (I didn't measure, less sensitive than Insights), and memory pressure remains more or less steady in the low teens of gigabytes.
### Testing
A/B testing and spot checking the data shows that nearly all data is either more correct or withing many-decimal-places rounding error.

Adds runtime events and analysis for generic meta data scopes. Any scope emitted on the "Metadata" writer will be analyzed and accessible in the metadata provider. Currently one built-in metadata type is provided: "Asset", which mimics LLMs implementation of asset tracking.

- "Trace/CpuProfile" -- captures allocation of per-thread buffers used by the cpu profiler trace.

Adds a new field type for trace events which contains a reference to a previously emitted event. In order to create a reference, the referenced event type needs to be declared with a new "definition" flag. The definition flag also defines type of id that is used for the reference, 8, 16, 32 and 64 bit values are supported.

Some rota items cannot make progress because their next event type is not known yet. They get moved to the end of the rota and the active count is decremented. There are two cases where the rota might be reprocessed from the beginning again; when an initial serial is set, and when the rota shows it has the next event. It is possible that on a subsequent pass through the rota, items that could not make progress previously might be able to this time. However, because the active count was left over from before they were excluded and OnData() would not do all the work it could possibly do.
All this only applies to old P2 traces.

Newer protocol traces consume as much data as they can before returning from OnData(). Older protocol support however can return will data still to process that will be continued on the next OnData() call. However, if the end of input stream has already been met the subsequent OnData() call is not made. The bug's always been present but hidden by a small input buffer.

If TCHAR happens to change to something other than a 16bit integer (e.g. because wchar_t is four bytes on a platform, or because the engine changes to UTF8), the analysis engine will no longer be able to read traces with char16_t-type strings.

- Implemented move-constructor/assignment operator. Transport keeps an array threads, each of which of owns a FStreamBuffer instance. When Transport resizes this array, it copies items about. Because there are no move constructors, the compiler ends up cloning FStreamBuffers (via copy-constructing) and incorrectly deleting Buffer pointers still in use.
