`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.
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.
Previously we didn't properly exclude $<COMPILE_ONLY:OBJECT lib>
from the right hand side of `target_link_libraries`.
Fix the update that commit 73337cb383 (LINK_LIBRARIES: Evaluate
separately for linking and usage requirements, 2022-03-22,
v3.24.0-rc1~404^2~2) made to `AddObjectEntries`.
Fixes: #26642
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.
