<#
.SYNOPSIS
    Collect the list of PDBs built in this repo, after converting them from portable to Windows PDBs.
.PARAMETER Path
    The root path to recursively search for PDBs.
.PARAMETER Tests
    A switch indicating to find test-related PDBs instead of product-only PDBs.
.PARAMETER ConvertToWindowsPDBs
    A switch to convert and return paths to Windows PDBs instead of portable PDBs.
    Ignored on non-Windows agents.
