Bump Folly to 2023.08.07.00 (#39798)

Summary:
This bumps folly, to absorb facebook/folly@45fffa6 which fixes warnings in XCode 15, and NDK 26 (treated as error bc we have better hygiene there). We then bump a little bit further to get past a new warning added, then fixed later.

Need to manually set `FOLLY_HAVE_GETTIME` on Apple because of the silliness described in facebook/folly#1470 (comment)

There is not a combination of Folly, and Android libc++, that has fixes for warnings, but doesn't require the new libc++ in NDK 26. It is expected then that this commit will fail the build, but the next should succeed, and the two must be landed at the same time.
