Changing the data storage of WebCore::Length to a std::variant would increase sizeof(Length)
because of padding, but I achieved the same goal for serialization by making a variant accessor
and a constructor that takes a variant.

* Source/WebCore/platform/Length.cpp:
(WebCore::Length::typeFromIndex):
(WebCore::Length::Length):
(WebCore::Length::ipcData const):
(WebCore::Length::floatOrInt const):
* Source/WebCore/platform/Length.h:
* Source/WebKit/Shared/WebCoreArgumentCoders.cpp:
(IPC::ArgumentCoder<Length>::encode): Deleted.
(IPC::ArgumentCoder<Length>::decode): Deleted.
