Plugin Trace Log implementation

[mkholt]

Evaluate ITracingService messages via String.Format and expose collected trace log

Trace messages with format args are now evaluated through String.Format so
invalid format strings surface during testing instead of being silently
swallowed. Arg-less messages remain verbatim, matching platform behavior.

Trace messages are also collected by the default tracing service factory and
exposed via XrmMockupBase.TraceLog (with ClearTraceLog) so tests can assert on
emitted trace output.

Group trace messages per plugin execution via PluginTraceLog

Trace messages are now grouped by the plugin execution that produced them,
mirroring the plugintracelog records of a real Dynamics 365 environment. Each
XrmMockupBase.PluginTraceLog entry captures the invoking type, message name,
primary entity, operation type, depth, correlation id, mode, request id,
execution start time, duration, the ordered list of trace messages and any
exception details.

PluginTrigger now times each sync/async plugin execution, captures thrown
exceptions and records an entry with the execution's own trace messages.
Internal XrmMockup system plugins are excluded. Configuration/secure
configuration and plugin step ids are not modeled by XrmMockup and remain null.

Extend grouped trace log to custom APIs and workflow activities

The per-execution trace grouping introduced for plugins now also covers custom
API executions and workflow activity executions (sync and async). A shared
PluginTraceRecorder helper centralizes the timing, exception capture and trace
message collection used by all three paths; CustomApiManager and WorkflowManager
now route their executions through it.

Custom API entries record the request name as the message and Plugin operation
type; workflow entries record the workflow name as the type, WorkflowActivity
operation type and the workflow's sync/async mode. Directly-invoked workflows
(ExecuteWorkflowRequest, which has no plugin context) are executed but not logged.

Pull request overview

Adds first-class trace capture to XrmMockup365 so tests can assert on emitted ITracingService output, and introduces a Dynamics-like per-execution “plugin trace log” (including custom APIs and workflow activities) with timing and exception details.

Changes:

• Evaluate ITracingService.Trace(format, args) via string.Format (when args provided) and expose a collected flat TraceLog on XrmMockupBase.
• Record grouped per-execution trace entries (PluginTraceLog) for plugins/custom APIs/workflow activities via a shared PluginTraceRecorder.
• Extend tests and test assemblies to validate formatting behavior, flat trace collection, grouped trace metadata, and exception capture.
