Refactor transaction checks in switch interpreter.

Prepare for moving the transactional interpreter from
`runtime/` to `dex2oat/` by moving transaction checking code
to a new file `active_transaction_checker.h`, and breaking
unstarted runtime dependency on transaction code by adding
an indirection with a virtual call through `ClassLinker`.

Consistently return the same value from contraint checks.
Previously we were returning the negated result from the
`CheckWrite{,Value}Constraint()` compared to the value we
received from `Transaction::Write{,Value}Constraint()`.

Test: m test-art-host-gtest
Test: testrunner.py --host --interp-ac
