rhi autotest: Do not read back an uninitialized cubemap face

renderToTextureCubemapFace reads back not only the face it renders
into, but also another one, in order to verify that the layer
parameter is not ignored. That face was never written to, and so the
results of reading it back are undefined. With D3D12 it also makes the
debug layer complain, because the subresources of a placed resource
must be initialized with a Discard, Clear, or Copy operation before
they can be used for anything else.

Upload a known content to that face instead. This is a Copy, so it
initializes the subresource, and it makes the readback result
deterministic, which allows checking the uploaded color as well.

Pick-to: 6.8

visionOS: Use the Swift driver to generate the bridging header

We were invoking swiftc with -frontend, which bypasses the driver.
The driver is what works out the macro plugin search paths for the
target platform, passing -plugin-path, -external-plugin-path, and
-in-process-plugin-server-path on to the frontend.

Without them the frontend can't expand any Swift macros, which broke
as of the Xcode 27 SDKs, where SwiftUI's @State is a macro rather
than a property wrapper:

    error: external macro implementation type 'SwiftUIMacros.StateMacro'
    could not be found for macro 'State()'; plugin for module
    'SwiftUIMacros' not found

Passing the plugin paths ourselves is not much of an option, as
SwiftUIMacros lives in the platform directory rather than the
toolchain, so it needs the per-platform -external-plugin-path with
the plugin server path appended. We let the driver work it out.
