Original change's description:
> Update bots' NDK to r26b
>
> Our NDK was several years out of date, so it was missing newer APIs.
> The last time we tried an update, it caused ASAN issues on the tree:
>     https://skia-review.googlesource.com/c/skia/+/439336
>
> Like that attempt, this changes the Mac create script, because the
> NDK is now distributed as a DMG.
>
> Critically, this moves our Android bots from clang 9 (!) to 17.
