iOS: Default to the host architecture for simulator builds

When configuring Qt with -sdk iphonesimulator we would always pick
x86_64 as the target architecture, even on an Apple silicon host,
where the simulator runs arm64 binaries. Default to the host
architecture instead.

[ChangeLog][iOS] Qt builds for the iOS simulator SDK now default to
the host architecture, instead of always defaulting to x86_64.

rhi: d3d: Do derefAdapter while the LUID is still valid

Calling the function after adapterLuid is nulled out is clearly
not ideal.

Enable Clang module maps by default on Apple and native Unix platforms

The module maps no longer affect C++ consumers, as we now mask them via
a VFS overlay for consumers that build with Clang modules, so we can
turn them on by default instead of requiring an explicit opt-in.

We limit this to Apple platforms, and Unix platforms we're not cross
compiling for. The maps are only ever picked up by Clang and Swift
consumers, which we don't expect for the likes of Android, WebAssembly,
or OHOS, and we're not generating them for Windows yet. Apple platforms
are included even though everything but macOS is cross compiled there,
as that's exactly where we expect Swift consumers to show up.

We restrict the module map test to Apple platforms at the same time, as
it builds Qt as a Clang module with -Werror, which requires a modular
C++ standard library. That's a given with libc++ on Apple platforms, but
not with the standard libraries used elsewhere, which is the same reason
the accompanying masking test was already restricted to Apple.

For now we don't enable the apinotes/swiftinterface interoperability
layer, as we haven't decided if this will live in Qt itself or in a
dedicated swift-package-manager Qt package.
