Upstream Boost 1.70 and above provide a proper `BoostConfig.cmake`
package configuration file. Packages for all major distros now
provide it in at least one LTS release. Add a policy to pretend
that the `FindBoost` module does not exist so that projects calling
`find_package(Boost)` use the upstream package directly.

Package configuration files generated by `configure_package_config_file`
set this variable in `@PACKAGE_INIT@` and then use it later. There may
be intervening calls to `find_package`, e.g., via `find_dependency`.
If the loaded package also used `configure_package_config_file`, it
may change the value of `PACKAGE_PREFIX_DIR`. Explicitly save and
restore the value to avoid this.

`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 12.
The `FindPythonInterp` and `FindPythonLibs` modules have been deprecated
since CMake 3.12. Add a policy to pretend they do not exist in order to
encourage projects to port to `FindPython` or `FindPython{2,3}`.
The `FindCUDA` module has been deprecated since CMake 3.10.
Add a policy to pretend it doesn't exist in order to encourage
projects to port away from it.
Extend commit eb35d8884b (find_package: Use PackageName_ROOT variables
as search prefixes, 2018-03-15, v3.12.0-rc1~349^2) to also check
upper-case `<PACKAGENAME>_ROOT` variables. Add policy `CMP0144` to
enable the behavior in a compatible way.
Fixes: #24403
Extend the LCC warning suppression from commit 08e7fb3cfa
(cmFindPackageCommand: Compile-time path generator expressions,
2022-07-05, v3.25.0-rc1~361^2~5) to cover a new number for the
same warning, now produced by LCC 1.26.15.
The `PREFIX/(Foo|foo|FOO).*/(cmake|CMake)/(Foo|foo|FOO).*/` search
path is the similar to the one already exists
`PREFIX/(Foo|foo|FOO).*/(lib/ARCH|lib*|share)/cmake/(Foo|foo|FOO).*/`.
The point is that `cmFileListBlahBlahGenerator` actually "generate"
directory names and never files.
The `cmBlahBlahStringGenerators` produce paths in fact. Ok, paths
nowadays are also strings but...
The `cmFileListGeneratorProject` and `cmFileListGeneratorMacProject`
was look very similar 'cept few lines.
Now they have a base class and the generator-specific logic has moved
to overrides.
Original code had path generators built at run-time using a linked list
of dynamically allocated nodes each of which was responsible to generate
a path segment.
However, the combination of used generators is totally well known at
compile time.
The `cmFindPackageFileList` instances always constructed w/ the only
parameter. The boolean flag is always `true` (default value).
Also, `cmFindPackageCommand::InitialPass` adds an empty string
to the `cmFindPackageCommand::SearchPathSuffixes` vector. Meaning
that `cmFindPackageCommand::CheckDirectory()` gonna be called for
the suffix-less path, so `cmFindPackageFileList::Visit` may call
only `cmFindPackageCommand::SearchDirectory` and get the same result.
They are unique by design. I.e., when the algorithm iterates over
args doing only one push per iteration indices gonna be unique ;-)
So, no need for `std::set` here.
Rename the booleans 's_ErrorOccured' and 's_FatalErrorOccured' to
's_ErrorOccurred' and 's_FatalErrorOccurred', respectively.
Rename the getters and setters to 'Get[Fatal]ErrorOccurred' and
'Set[Fatal]ErrorOccurred', and fix all uses across the codebase.
