What does this PR do?

Fixes a Set-StrictMode -Version Latest failure in Get-GmsaScheduledTask.ps1 when a
Scheduled Task uses a COM-handler action.

Scheduled Task actions come in two CIM types:

MSFT_TaskExecAction - exposes Execute, Arguments, WorkingDirectory.
MSFT_TaskComHandlerAction - exposes ClassId, Data (no Execute).

The Actions block read .Execute unconditionally. Under StrictMode, accessing a property
that does not exist is a terminating error, so any host with a COM-handler task (for example
the built-in .NET Framework NGEN tasks) failed with:

The property 'Execute' cannot be found on this object. Verify that the property exists.

This adds a StrictMode-safe Get-CimPropertyValue helper that probes PSObject.Properties
before reading, and reports ActionType plus ComClassId / ComData alongside the existing
exec fields.

Fixes #

How was this tested?

Parser validation - 0 errors for the changed .ps1 file
Manually tested on a host with 230 tasks, 114 of which use COM-handler actions (via
-Recurse). Before: threw on the first COM-handler task. After: all tasks report without
error, COM-handler actions show their ActionType and ComClassId.

## What does this PR do? Fixes a `Set-StrictMode -Version Latest` failure in `Get-GmsaScheduledTask.ps1` when a Scheduled Task uses a COM-handler action. Scheduled Task actions come in two CIM types: - `MSFT_TaskExecAction` - exposes `Execute`, `Arguments`, `WorkingDirectory`. - `MSFT_TaskComHandlerAction` - exposes `ClassId`, `Data` (no `Execute`). The Actions block read `.Execute` unconditionally. Under StrictMode, accessing a property that does not exist is a terminating error, so any host with a COM-handler task (for example the built-in `.NET Framework NGEN` tasks) failed with: > The property 'Execute' cannot be found on this object. Verify that the property exists. This adds a StrictMode-safe `Get-CimPropertyValue` helper that probes `PSObject.Properties` before reading, and reports `ActionType` plus `ComClassId` / `ComData` alongside the existing exec fields.

Fix StrictMode error on COM-handler task actions in Get-GmsaScheduledTask 211dbb5e09

Get-ScheduledTask actions can be MSFT_TaskExecAction (Execute/Arguments/
WorkingDirectory) or MSFT_TaskComHandlerAction (ClassId/Data). The Actions block
read .Execute unconditionally, so under Set-StrictMode -Version Latest a task with
a COM-handler action threw 'The property Execute cannot be found on this object.'

Add a StrictMode-safe Get-CimPropertyValue helper that probes PSObject.Properties,
and report ActionType plus ComClassId/ComData alongside the exec fields. Verified
against a host with 114 COM-handler tasks: all now report without error.
