[3.11] gh-105967: Work around a macOS bug, limit zlib C library crc32 API calls to 1gig (GH-112615) (#112725)

gh-105967: Work around a macOS bug, limit zlib C library crc32 API calls to 1gig (GH-112615)

Work around a macOS bug, limit zlib crc32 calls to 1GiB.

Without this, `zlib.crc32` and `binascii.crc32` could produce incorrect
results on multi-gigabyte inputs depending on the macOS version's Apple
supplied zlib implementation.
(cherry picked from commit 4eddb4c9d9452482c9af7fa9eec223d12b5a9f33)
