Add support for PartionRealloc to return nullptr
Currently the PartitionRealloc code path will only exit, with no
option to return nullptr on failure, unlike PartitionAlloc code path.
This CL refactors the realloc code path to be similar to alloc code
path, following the upstream patch:
https://chromium-review.googlesource.com/c/chromium/src/+/1044971
This also changes the version of realloc exposed to third party C libs
to have the nullptr behaviour, like the exposed version of alloc.
This CL is a redo of
https://pdfium-review.googlesource.com/c/pdfium/+/31990
