In embedded mode, we mustn't have references to the C++ library, because
some embedded platforms don't include the C++ library.
Additionally, it's good to avoid use of global operator new and operator
delete, because they can be globally overridden and this has bitten us
in the past.

`__msvc_bit_utils.hpp` was added in a recent version of MSVC, and it is causing build errors for SwiftCompilerSources:
```
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\include\numeric:598:12: error: function '_Select_countr_zero_impl<unsigned long long, (lambda at C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\include\numeric:598:55)>' with deduced return type cannot be used before it is defined
return _Select_countr_zero_impl<_Common_unsigned>([=](auto _Countr_zero_impl) {
```
This change references the `__msvc_bit_utils.hpp` header from the modulemap. Since we still need to support older versions of Visual Studio that do not provide `__msvc_bit_utils.hpp`, this also teaches ClangImporter to inject an empty header file named `__msvc_bit_utils.hpp` into the system include directory, unless it already exists.

This adds an automatic conformance for `std::map` and `std::unordered_map` to Swift's `ExpressibleByDictionaryLiteral` protocol.
This makes it possible to pass a dictionary literal as an argument to a function that takes a `std::map` as parameter.

Swift's own `Set` conforms to `ExpressibleByArrayLiteral`. This change conforms instantiations of C++ `std::set` to `ExpressibleByArrayLiteral` as well.
This makes it possible to pass an array literal as an argument to a function that takes a `std::set` as parameter.

We have been only including a subset of files and functionality on Embedded Concurrency, let's instead include all the
source files, and have a fine grained opt out on things that don't yet work. Namely, this is still avoiding clocks, task
sleeping and custom executors.
Add a test for AsyncStream and continuations on Embedded Concurrency.
The way that we include COMPATIBILITY_OVERRIDE_INCLUDE_PATH freaks out the
syntax highlighting of editors like emacs. It causes the whole file to be
highlighted like it is part of the include string.
To work around this, this patch creates a separate file called
CompatibilityOverrideIncludePath.h that just includes
COMPATIBILITY_OVERRIDE_INCLUDE_PATH. So its syntax highlighting is borked, but
at least in the actual files that contain real code, the syntax highlighting is
restored.

An unmanaged property does not map to an operation in CVW, instead it will be copied like primitive values. When instantiating the layout string, we correctly do not emit an operation, but we compute the offset to the next field as if we did. This is causing the offset to be incorrect and subsequent operations to be executed on the wrong address, causing crashes or other misbehavior.
Define `NOMINMAX` and `WIN32_LEAN_AND_MEAN` when including `<Windows.h>`.
Don't export the interface from DLLs.
Make sure we include `<new>` when using placement operator new.

We were missing a field in `SwiftJob`, which broke various things. To
avoid that problem in future, this PR adds a set of static asserts to
check the layout of various structures and that we're using the same
values as well.
Also added some functions to the ABI, and fixed things so that if you
enable the debug logging the library still builds (there was an extra
`_` in `Actor.cpp` that caused a build failure).
Finally, renamed `Hooks.cpp` to `ConcurrencyHooks.cpp`.
