[ci] Opt in to symbol archiving during VS insertion (#6195)

Context: xamarin/yaml-templates#131

Enables conversion and archiving of symbol files during the VS insertion
stage.  Symbol archiving steps will only run if both the
`symbolArtifactName` parameter is provided, and `archiveSymbols` is set
to true.  The `symbolConversionFilters` parameter can be used to filter
out paths of symbol files that should not be converted/archived.
