[pytorch] Enable memory map file support for Android, Apple, and CXX (#88545) Summary: See title. Left Windows out so it still compiles. Test Plan: Add a `#fail` below [this line](https://fburl.com/code/p0mlhlw4) and build for various platforms and confirm it fails which proves the `#ifdef` was hit. ``` buck2 build xplat/langtech/tuna/cli:tuclixAndroid buck2 build xplat/langtech/tuna/cli:tuclix ``` CI/CD for the rest.
