  [PassBuilder] Add ThinLTO EP callbacks mirroring FullLinkTimeOptimizationEarly/Last (#221857)

Our downstream has a request to add customization pass into
ThinLinkTimeOptimizationEarlyEPCallback, but buildThinLTODefaultPipeline
has no equivalent EPCallback like buildLTODefaultPipeline does. This PR
add it and ThinLinkTimeOptimizationLastEPCallback as well.
