  [analyzer] Fix a crash from element region construction during `ArrayInitLoopExpr` analysis (#113570)

This patch generalizes the way element regions are constructed when an
`ArrayInitLoopExpr` is being analyzed. Previously the base region of the
`ElementRegion` was determined with pattern matching, which led to
crashes, when an unhandled pattern was encountered.

Fixes #112813
