Sync eng/common directory with azure-sdk-tools for PR 9102 (#1910)

* Add CompatibleConvertFrom-Yaml to common Package-Helpers
* Add CI artifact parsing to Save-Package-Properties, now each individual packageinfo.json file contains the relevant ci artifact lines for the package. This short circuits needing to re-parse this information in common checks.

+.SYNOPSIS
+This function is a safe wrapper around `yq` and `ConvertFrom-Yaml` to convert YAML content to a PowerShell HashTable object
+
+.DESCRIPTION
+This function wraps `yq` and `ConvertFrom-Yaml` to convert YAML content to a PowerShell HashTable object. The reason this function exists is
+because while on a local user's machine, installing a module from the powershell gallery is an easy task, in pipelines we often have failures
+to install modules from the gallery. This function will attempt to use the `yq` command if it is available on the machine, and only will install
+the yaml module if `yq` is not available. This means that for the majority of runs on CI machines, the yaml module will not be installed.
+
+.PARAMETER Content
+The content to convert from YAML to a PowerShell HashTable object. Accepted as named argument or from the pipeline.
+
+.EXAMPLE
+CompatibleConvertFrom-Yaml -Content (Get-Content -Raw path/to/file.yml)
+
+.EXAMPLE
+Get-Content -Raw path/to/file.yml | CompatibleConvertFrom-Yaml
