Makoto Kato 8a25b6b137 Bug 1618759 - Part 4. Use InputPane to open on-screen keyboard for Windows 10 RS1+. r=masayuki
Unfortunately, current on-screen keyboard (OSK) code in Gecko doesn't work on
current Windows 10. Actually, Windows automatically control OSK when getting
focus. But this isn't good for web browser since `inputmode` spec can close
OSK by `none` value.

Windows 10 RS1 has new API (IInputPane [*1]) to control software keyboard. So
we have to use it if OS is RS1 or later.

TSF has new flag as `TS_SD_INPUTPANEMANUALDISPLAYENABLE` not to control OSK by
TSF. We should use it.

IMM doesn't have this feature to manage OSK. This will become a limitation for
`inputmode` implementation.
