2b0dd88f1ce9084324dc54db578fade9c926fd71 depends: Ensure definitions are passed when building SQLite with DEBUG=1 (Hennadii Stepanov)

Pull request description:

  The `--enable-debug` configure option for the SQLite package does two things:
  ```autoconf
  #-----------------------------------------------------------------------
  #   --enable-debug
  #
  AC_ARG_ENABLE(debug, [AS_HELP_STRING(
    [--enable-debug], [build with debugging features enabled [default=no]])],
    [], [])
  AC_MSG_CHECKING([Build type])
  if test x"$enable_debug" = "xyes"; then
    BUILD_CFLAGS="$BUILD_CFLAGS -DSQLITE_DEBUG -DSQLITE_ENABLE_SELECTTRACE -DSQLITE_ENABLE_WHERETRACE"
    CFLAGS="-g -O0"
    AC_MSG_RESULT([debug])
  else
    AC_MSG_RESULT([release])
  fi
  #-----------------------------------------------------------------------
  ```

  It adds three preprocessor definitions and overrides `CFLAGS` with `"-g -O0"`. The latter breaks the user's ability to provide sanitizer and LTO flags.

  This PR might be especially useful for OSS-Fuzz where `DEBUG=1` has been used since https://github.com/google/oss-fuzz/pull/10503.

  Also it makes a workaround for building SQLite for 32-bit unneeded. For details, please refer to https://github.com/hebasto/oss-fuzz/tree/240120-sqlite.

  Changes in https://github.com/bitcoin/bitcoin/pull/29282 might not be strictly required now. However, I consider them an improvement.
