Early WebProcess exit on 32-bit platforms since memory limit is zero

[psaavedra]

Describe the bug

Backport this patch from upstream: https://github.com/WebKit/WebKit/commit/b0895ea02d480a799a9826620683d6b49ccdaf21

In 250548@main, the memory limit in MemoryPressureHandler is set to a
least 7 GB for active process.
This value is stored in a size_t variable, but this is limited to 4 GB
on 32-bit platforms.

The memory limit is truncated down to 0, which triggers a WebProcess
exit after the first MemoryPressure check.
