Subject: [PATCH] feat(vimscript): scripts can detect 'android', 'termux'
 #38218

Problem:
The 'android' and 'termux' feature flags have been shipped in the
downstream neovim/neovim-nightly package for 5+ years but were never
properly documented in the downstream patch.

Solution:
Upstream the 'android' and 'termux' feature flags into Neovim as
decoupled feature flags, this enables the 'android' feature in
particular to be available independently of the 'termux' feature
for builds of Neovim against the Android NDK, but not including
the Termux NDK patchset.
