Expose still more WKPreferences SPI to match C SPI

• Component: WebKit API
• Status: RESOLVED FIXED

[Jeff Miller]

Add the following properties to the WKPreferences SPI:

_allowsInlineMediaPlayback
_applePayEnabled
_avFoundationNSURLSessionEnabled
_dnsPrefetchingEnabled
_inlineMediaPlaybackRequiresPlaysInlineAttribute
_invisibleMediaAutoplayNotPermitted
_legacyEncryptedMediaAPIEnabled
_lowPowerVideoAudioBufferSizeEnabled
_mainContentUserGestureOverrideEnabled
_mediaStreamEnabled
_needsStorageAccessFromFileURLsQuirk
_pdfPluginEnabled
_requiresUserActionForAudioPlayback
_requiresUserActionForVideoPlayback
_serviceControlsEnabled
_showsToolTipOverTruncatedText
_textAreasAreResizable
_useGiantTiles
_wantsBalancedSetDefersLoadingBehavior
_webAudioEnabled

Some of these are exposed by the WKPreferencesRef C SPI, but some (like _lowPowerVideoAudioBufferSizeEnabled) are not and are being implicitly set by values in Safari's Defaults.plist. When using WKWebView, this will no longer work since WebKit won't read preferences from Safari's defaults, so they need to be exposed via WKPreferences.

Correction, change _requiresUserActionForAudioPlayback to _requiresUserGestureForAudioPlayback and _requiresUserActionForVideoPlayback to _requiresUserGestureForVideoPlayback.

This is probably setting a bool in the wrong process.

This should always be enabled.

Good point. I don't think we can easily change this from the UI process. I'll remove this and talk to Jer about what he wants to do, e.g. maybe this deprecated setting should default to true anyway.

OK, I'll remove this as well.
