[InstCombine] foldVecExtTruncToExtElt - extend to handle... 

[InstCombine] foldVecExtTruncToExtElt - extend to handle trunc(lshr(extractelement(x,c1),c2)) -> extractelement(bitcast(x),c3) patterns. (#109689)

This patch moves the existing trunc+extractlement -> extractelement+bitcast fold into a foldVecExtTruncToExtElt helper and extends the helper to handle trunc+lshr+extractelement cases as well.

Fixes #107404
