[Preferences] It should be possible to have different default values for WebKitLegacy and WebKit in preference yaml files
​https://bugs.webkit.org/show_bug.cgi?id=216987

Reviewed by Darin Adler.

Source/WebKitLegacy:

  • WebKitLegacy.xcodeproj/project.pbxproj:

Update script phase to explicitly specify the frontend (WebKitLegacy) and the templates to generate.

Source/WebKitLegacy/mac:

Add new syntax for default values that allows specializing based on both frontend (WebKit or
WebKitLegacy) and then futher based on platform macros. For example, the preference for
CSSTypedOMEnabled now looks like:

CSSTypedOMEnabled:

type: bool
humanReadableName: "CSS Typed OM"
humanReadableDescription: "Enable the CSS Typed OM"
webcoreBinding: RuntimeEnabledFeatures
condition: ENABLE(CSS_TYPED_OM)
defaultValue:

WebKitLegacy:

default: false

WebKit:

"ENABLE(EXPERIMENTAL_FEATURES) && (PLATFORM(GTK)
PLATFORM(WPE))": true

default: false

Which means that in WebKitLegacy, the default value is false, and in WebKit, the default
value will be:

#if ENABLE(EXPERIMENTAL_FEATURES) && (PLATFORM(GTK)
PLATFORM(WPE))

true

#else

false

#endif

As many platform macro based conditions can be provided as wanted, and they are evaluated
in the order specified in the file.

The syntax currently always requires explicitly specifying WebKitLegacy and WebKit and default
for each, even if they are all the same, but could be extended in the future to allow compaction
if that becomes desirable. There is also not yet support for conditionally enabling a feature
based on os-feature-flags or linked-on-or-after checks, so those still require specifying the
default value as a function, but that seems like a nice future improvement.

As this is still staging for doing this for both WebKitLegacy and WebKit, this change only effects
WebKitLegacy for now, and subsequent changes will move this to a shared location.
