Add XML documentation for Android.Gestures #82

The Android.Gestures namespace contains 216 To be added placeholders in source XML documentation (excluding docs\xml\index.xml).

Finishability

Finishability: not assessed. The TODO count does not establish whether official Android/Java reference comments exist for every remaining member. A source-coverage pass is still needed; if the official comments are exhausted, use a separately agreed completion approach (for example, reviewed authored documentation based on an authoritative source) rather than another importer pass.

Example command:

rg -n -i --glob 'Android.Gestures/**' --glob 'ns-Android.Gestures.xml' 'to be added' docs\xml
