patch 9.2.0191: Not possible to know if Vim was compiled with Android support

Problem:  The "android" and "termux" feature flags have been shipped in
          Termux's downstream vim / vim-gtk package for 5+ years but were
          never properly documented in the downstream patch.
Solution: Upstream the "android" and "termux" feature flags into Vim as
          decoupled feature flags, this enables the "android" feature in
          particular to be available independently of the "termux"
          feature for builds of Vim against the Android NDK, but not
          including the Termux NDK patchset.

closes: #19623
