`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.
This adds the following new arrays, which together capture all direct
dependencies and interface dependencies of a target:
- linkLibraries
- interfaceLinkLibraries
- compileDependencies
- interfaceCompileDependencies
- objectDependencies
- orderDependencies

The cmLinkImplItem class used to contain some additional members
to support the CMP0027 policy. Since the CMP0027 policy and those
associated members were removed, the cmLinkImplItem class has been
a plain wrapper around cmLinkItem with no additional members.
It is no longer needed and cmLinkItem can be used directly wherever
cmLinkImplItem was used previously.
Extend commit e8010b67c7 (cmGeneratorExpressionDAGChecker: Make local
generator available in constructor, 2024-04-25, v3.30.0-rc1~172^2~6) and
commit 633afa0b2e (cmGeneratorExpressionDAGChecker: Make config name
available in constructor, 2024-05-08, v3.30.0-rc1~82^2~2) to make the
full evaluation context available in the constructor.
Fix logic from commit b9ee79b8a1 (GenEx: Add support for custom
transitive compile properties, 2024-05-09, v3.30.0-rc1~82^2~1) to more
precisely know when we are computing the link dependency graph.

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
Since commit c16acd35b3 (GenEx: Add support for custom transitive link
properties, 2024-05-09, v3.30.0-rc1~82^2) evaluation of
`TRANSITIVE_LINK_PROPERTIES` by `install(EXPORT)` enables discovery of
missing dependencies on INTERFACE libraries that we did not previously
diagnose. This regressed existing projects that relied on such
non-diagnosis. Although commit 2fc9e482a9 (Evaluation of
TRANSITIVE_LINK_PROPERTIES isn't considered a usage, 2024-07-05) fixed
this, it also made a significant change to the `UseTo` infrastructure
that may have other subtle effects. Replace the fix with an approach
that explicitly models suppression of the relevant diagnostics.
Fixes: #26108
Teach the `$<TARGET_PROPERTY:...>` generator expression to check for a
new `TRANSITIVE_COMPILE_PROPERTIES` property in the target's link
closure to enable transitive evaluation of named properties through
the link closure, excluding entries guarded by `$<LINK_ONLY:...>`.
Issue: #20416
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>`.
