Report deduplicated reference count, deflake EventSource schema tests

TypeSystemInitStop now reports the size of the final reference set passed
to Init() instead of the raw resolve count, which included same-name
duplicates that the version dedup later drops. The schema smoke tests
asserted exact global event counts, but the providers are process-wide
and the decompiler fixtures run in parallel, so unrelated decompilations
could inflate the counts; every string payload now carries a unique
marker (and the string-less snapshot events a sentinel count) that the
assertions filter on.

Redesign DecompilerEventSource with Start/Stop tracing and keyword gating

The events introduced in #2519 timed only the five per-entity DoDecompile
overloads, allocated a Stopwatch and the member's FullName even when no
trace session was attached, and reported whole milliseconds, which rounds
almost every member to zero. Flat one-shot events also gave PerfView and
dotnet-trace no way to show durations or nesting, and the actually
expensive stages (type system initialization, assembly resolution probing,
the IL/AST transform pipelines, whole-project decompilation) were not
instrumented at all.

Start/Stop event pairs let trace viewers derive duration and nesting from
event timestamps, keywords let a session enable only the areas of
interest, and every call site is gated on IsEnabled() so tracing costs a
branch when disabled. Per-transform events are Verbose because of their
volume; unlike the STEP/Stepper mechanism they work in Release builds.
EventSource is in-box for netstandard2.0 and flows over both ETW and
EventPipe, so this stays cross-platform with no new dependency.
