4a825039a509c43ba20b2cd7aab448b3be16bcc3 build: use _LIBCPP_ENABLE_DEBUG_MODE over ENABLE_ASSERTIONS (fanquake)

Pull request description:

  `_LIBCPP_ENABLE_ASSERTIONS` is deprecated, and will be removed. [See (from libc++ __config in main)](b57df9fe9a/libcxx/include/__config (L205-L209)):

  > TODO(hardening): remove this in LLVM 19.
  > This is for backward compatibility -- make enabling `_LIBCPP_ENABLE_ASSERTIONS` (which predates hardening modes)
  > equivalent to setting the safe mode.
  > ifdef _LIBCPP_ENABLE_ASSERTIONS
  > warning "_LIBCPP_ENABLE_ASSERTIONS is deprecated, please use _LIBCPP_ENABLE_SAFE_MODE instead."

  From LLVM 17, `_LIBCPP_ENABLE_DEBUG_MODE` can be used instead, which also performs more checks than safe mode:

  > Enables the debug mode which contains all the checks from the hardened mode and additionally more expensive checks that may affect the complexity of algorithms. The debug mode is intended to be used for testing, not in production. Mutually exclusive with `_LIBCPP_ENABLE_HARDENED_MODE` and `_LIBCPP_ENABLE_SAFE_MODE`.

  See https://libcxx.llvm.org/Hardening.html.

  Related to #28476.
