docs: Replacing {#link with {@link

Several java files had the typo {#link (for cross-references to other
Javadocs) instead of the proper {@link format. This was confusing the
new doc publish tool (Mivi) since that's the format used for {# Django
comments #}.

Fixed a couple of links that had other errors (which prevented building
once the {# -> {@ was done) and other typos.

Replaced throughout the frameworks/base project; I'll need a separate CL
for the AndroidX fixes.

Staged to:

go/dac-stage/reference/android/app/Instrumentation.html
go/dac-stage/reference/android/bluetooth/BluetoothAdapter.html
go/dac-stage/reference/android/bluetooth/BluetoothDevice.html
go/dac-stage/reference/android/bluetooth/BluetoothServerSocket.html
go/dac-stage/reference/android/inputmethodservice/InputMethodService.html
go/dac-stage/reference/android/view/KeyCharacterMap.html
go/dac-stage/reference/android/view/KeyEvent.html
go/dac-stage/reference/android/media/AudioManager.html
go/dac-stage/reference/android/net/wifi/WifiConfiguration.html

(Other files were not in the public Javadocs.)
