  [flang][debug] Make common blocks data extraction more robust. (#168752)

Our current implementation for extracting information about common block
required traversal of FIR which was not ideal but previously there was
no other way to obtain that information. The `[hl]fir.declare` was
extended in commit https://github.com/llvm/llvm-project/pull/155325 to
include storage and storage_offset. This commit adds these operands in
`fircg.ext_declare` and then use them in `AddDebugInfoPass` to create
debug data for common blocks.
