In debug builds, we assert and abort to give more useful crashes for
development (i.e., instead of triggering UB). Otherwise, we get the
optimization benefits of `unreachable()` (or the older
platform-specific fallbacks per `cm/utility`).
Move some target related enumeration types from `cmStateTypes.h` to a
new header, as these really aren't "state" types. Also, make
`TargetType` a strongly-typed enumeration.
`include-what-you-use` diagnostics, in practice, are specific to
the environment's compiler and standard library. Update includes
to satisfy IWYU for our CI job under Debian 13. Some patterns:
* Types named in virtual `override` signatures no longer require
includes since the overridden signature already names them.
* A function argument's type needs to be included even if its constructor
is called only by implicit conversion. For example, constructing a
`std::function` from a lambda now requires `<functional>`.
* Some prior mysterious `<type_traits>` inclusions are no longer required.
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`, now with "east const" enforcement.
Use `clang-format` version 18.

Issue: #26123
Previously this method always returned the closure for compile-only
usage requirements. Add an option to get the closure for linking, which
pierces `$<LINK_ONLY>`.
