Support TraceLogging formatting hints

[chwarr]

Trace Data Helper lets you add display hints to fields in events. For example, there are hints to indicate that an integer value should hex formatted on display or that the value is a HRESULT. The commonly used C++ TraceLogging library supports these hints via its TraceLogging Wrapper macros.

Add support for pretty printing the following _TDH_OUT_TYPE values:

• TDH_OUTTYPE_HEXINT8 - hex, width of the underlying type
• TDH_OUTTYPE_HEXINT16 - hex, width of the underlying type
• TDH_OUTTYPE_HEXINT32 - hex, width of the underlying type
• TDH_OUTTYPE_HEXINT64 - hex, width of the underlying type
• TDH_OUTTYPE_PID - decimal number without digit seperators
• TDH_OUTTYPE_TID - decimal number without digit seperators
• TDH_OUTTYPE_PORT - decimal number without digit seperators, converted from network byte order
• TDH_OUTTYPE_IPV4 - dotted quad
• TDH_OUTTYPE_IPV6 - colon-seperated, elision of runs of zeros
• TDH_OUTTYPE_SOCKETADDRESS - "address:port" for AF_INET and AF_INET6
• TDH_OUTTYPE_ERRORCODE - hex, no padding
• TDH_OUTTYPE_WIN32ERROR - hex, no padding
• TDH_OUTTYPE_NTSTATUS - hex, always 8 digits wide
• TDH_OUTTYPE_HRESULT - hex, always 8 digits wide
• TDH_OUTTYPE_CODE_POINTER - lowercase hex, minimum of 8 digits wide

Fixes #2436.

Given TraceLogging code like this:

TraceLoggingWrite(
    g_hMyProvider,
    "MyEvent",
    TraceLoggingUInt32(value1ToLog),
    TraceLoggingHexUInt32(value2ToLog));

In PerfView today, this would be rendered as

    value1ToLog="1" value2ToLog="32,769"

Now, it is rendered as

    value1ToLog="1" value2ToLog="0x00008001"

Visually, before:

and after:

For things like flags these format hints can make it easier to read values at a glance. There are also common values that are represented in hex, like PCI IDs.

When PerfView already had support for formatting a value, its existing formating style was followed. Otherwise, I matched WPA's formatting.

Changes made:

• Changed TraceEvent's representation of the output type from a ushort to the new TdhOutputType enum.
• Add TdhFormtter.cs that knows how to format a value with a given formatting hint. A formatting hint was chosen so that the PayloadFetch object didn't need to remember both its TdhInputType and its TdhOutputType.
• Reved the FastSerializable format to include the new formatting hint.
• Introduced a new FormatUtils helper for shared formatting code between TraceEvent.cs and DynamicTraceEventParser.cs
• Unit tests for the new formatting logic added.
• Updated the baseline files to capture the changes in formatting.
