Message:

ENABLE_LEGACY_CSS_VENDOR_PREFIXES and RuntimeEnabledFeatures::legacyCSSVendorPrefixesEnabled() don't do anything
​https://bugs.webkit.org/show_bug.cgi?id=217833

Reviewed by Simon Fraser.

Source/WebCore:

Remove support for ENABLE_LEGACY_CSS_VENDOR_PREFIXES, which only guarded code
that also checked legacyCSSVendorPrefixesEnabled(), which was never enabled.

• css/CSSStyleDeclaration.cpp:
• css/parser/CSSPropertyParser.cpp:

(WebCore::cssPropertyID):

• page/RuntimeEnabledFeatures.h:

(WebCore::RuntimeEnabledFeatures::setLegacyCSSVendorPrefixesEnabled): Deleted.
(WebCore::RuntimeEnabledFeatures::legacyCSSVendorPrefixesEnabled const): Deleted.

Source/WTF:

• wtf/PlatformEnable.h:
• wtf/PlatformEnableCocoa.h:

Remove support for ENABLE_LEGACY_CSS_VENDOR_PREFIXES, which only guarded code that was always disabled.
