### Description
Disable CPU EP's allocator's arena when address sanitizer is enabled,
because it masks problems. For example, the code in
onnxruntime/test/quantization/quantization_test.cc has a memory leak
problem: it allocated a buffer but didn't free it, but most memory leak
check tool cannot detect that because the buffer was from an arena and
the arena was finally freed.
### Motivation and Context
Provider better memory leak check coverage.
