LOG: [flang][HLFIR] Adapt InlineElementals to run on all top level ops (#92734)

This means that this pass will also run on hlfir elemental operations
which are not inside of functions.

See RFC:

https://discourse.llvm.org/t/rfc-add-an-interface-for-top-level-container-operations

Some of the changes are from moving the declaration and definition of
the constructor into tablegen (as requested during code review of
another pass).

While I was updating the tests I noticed that the optimized
bufferization pass and some cse were missing from the optimized pipeline
in flang/test/Driver/mlir-pass-pipeline.f90. I fixed this in this
commit.
