Revert "Use partition_alloc PA_BUILDFLAG(...) #cleanup"

This reverts commit 45c8cf50cad9ea22e36fcff04043ae966a6bd583.

Reason for revert: Speculative revert given https://issuetracker.google.com/issues/339074799?pli=1
I am pretty sure this isn't related, but this doesn't hurt reverting
to be sure.

Original change's description:
> Use partition_alloc PA_BUILDFLAG(...) #cleanup
>
> Automated #cleanup patch.
>
> Migrate:
> - from  BUILDFLAG (legacy chromium macro)
> - to PA_BUILDFLAG (new partition_alloc macro)
> in the partition_alloc library.
>
> Follow-up will:
> - Update chrome.
> - Update dawn
> - Update pdfium;
>
> Why No-Try. Touching partition_alloc, even with empty lines causes
> unrelated failing tests. They are usually not executed on the CQ, and
> the CI uses a different configuration. Example:
> https://chromium-review.googlesource.com/c/chromium/src/+/5513777
> I am discussing with Infra how to best improve the CQ to detect those
> issue early, and move the workload to a CI sheriff.
>
> Feel free to revert this patch if some a bots fails two consecutive
> run.
