Revert^2 "Remove support for Valgrind in ART."
- Disable test configuration art-gtest-valgrind64
(art-gtest-valgrind32 was already disabled).
- Remove Makefile logic regarding testing with Valgrind.
- Remove occurrences of `TEST_DISABLED_FOR_MEMORY_TOOL_VALGRIND`.
- Replace occurrences of `TEST_DISABLED_FOR_MEMORY_TOOL_ASAN` with
`TEST_DISABLED_FOR_MEMORY_TOOL`.
- Replace the potentially dynamically evaluated
`RUNNING_ON_MEMORY_TOOL` expression with constant
`kRunningOnMemoryTool`.
- Simplify and fold the logic of
`art::ArenaAllocatorMemoryToolCheckImpl` and
`art::ArenaAllocatorMemoryToolCheck` into
`art::ArenaAllocatorMemoryTool`.
- Adjust comments regarding memory tools.
- Remove Valgrind suppression files.
- Remove `--callgrind` option from tools/art.
