Update NDK to 26.0.10792818 (#17852)

### Description
Update NDK to 26.0.10792818 which is included in every macOS build
machine so that we do not need to download a different version every
time in every build.

### Motivation and Context
Downloading NDK on-the-fly is a main contributor of Android related
build failures.
