Add a patch file to fix zoneinfo64 parsing on big endian platforms

On big endian platforms ICU4C provides data in native BE order causing
ZoneInfo64 parsing to fail with "Failed to load timezone info" and is
causing test failures on Node.js after enabling temporal on BE:
nodejs/node#61808

This CL uses `from_ne_bytes` to read data in native endian order
instead.

Patch is also applied to ICU4X upstream:
unicode-org/icu4x#7658
