MOF Files are identified incorrectly

Pull Request

Pull Request (PR) description

The task Build_DscResourcesToExport_ModuleBuilder did not properly look for DSC MOF-based resources and DSC composite resources. It uses Get-ChildItem -Include '*.schema.mof' -File which in some cases returns more than just *.schema.mof files.

https://github.com/gaelcolas/Sampler/blob/0df39036bac42ecdf15ed956d8bc5e3fc30995c7/.build/tasks/Build-Module.ModuleBuilder.build.ps1#L359

Discovering the name of DSC composite resources must be done differently, hence a Get-Psm1SchemaName.ps1 was added.

The changes of this PR mainly add support for DSC composite resources.

Fixed

• 402: Using parameter Filter instead of Include to get MOF files.

Added

• Support for DSC composite resources.
