Swift WebBackForwardList (off by default) - xcconfig changes

Reviewed by Richard Robinson.
We're introducing a Swift version of the Back Forward List. For the general
design and rationale, see
https://github.com/WebKit/WebKit/pull/55393
It will be landed as a series of separate commits in order to ease code review.
In this commit, we make the required xcconfig changes. As this Swift
implementation is off-by-default, nothing happens here unless
ENABLE_BACK_FORWARD_LIST_SWIFT is specified in LocalOverrides.xcconfig. If
that's specified, we pass this as a preprocessor definition, and we also pass
an extra flag to swiftc: -emit-clang-header-min-access internal. This allows us
to expose non-public Swift functions and types to C++, and is crucial to avoid
needing to pub the language boundary into WebKit's public API.
We are adding these config flags separately in order to ease code review of
subsequent stages. It's not useful until later commits also land.
It should however be harmless meanwhile.
