…ythonGH-140111) Fix memory leak in sub-interpreter creation caused by overwriting of the previously used `_malloced` field. Now the pointer is stored in the first word of the memory block to avoid it being overwritten accidentally.

This patch fixes a memory leak detected by AddressSanitizer during subinterpreter creation.
The original allocation pointer is now stored before the aligned memory block, removing
the need for the _malloced field in PyInterpreterState.
Thanks to @kumaraditya303 for highlighting the pointer overwrite issue.
Fixes #140067
