Move Rails-main Gemfile to top level and add gemfiles/Gemfile.activerecord-8.1

Top-level Gemfile now tracks Rails main (rails/rails:main) and the
oracle-enhanced adapter master (rsim/oracle-enhanced:master),
mirroring how the previous gemfiles/Gemfile.activerecord-main pulled
in bleeding-edge dependencies. Picking up rails/rails main as the
default development target surfaces upstream regressions earlier
than waiting for a released Rails line.

Add gemfiles/Gemfile.activerecord-8.1 pinned to ~> 8.1.0 (matching
the style of Gemfile.activerecord-8.0) and wire it into
.github/workflows/test_gemfiles.yml so 8.1 gets the same matrix
coverage the other released Rails lines have.

Remove the redundant gemfiles/Gemfile.activerecord-main; tracking
Rails main now happens in the top-level Gemfile.
