Adds a parser and serializer for the EcoStd Module Metadata format
RFC: https://github.com/ecostd/rfcs/pull/3
This adapts the existing experimental support for import std; to use
the new parser. The CMAKE_CXX_STDLIB_MODULES_JSON is now the canonical
variable for controlling how CMake discovers the stdlib module metadata,
and is used directly by compiler detection.
Toolchains can still override the __CMAKE::CXX## targets if they wish,
either in conjunction with CMAKE_CXX_STDLIB_MODULE_JSON or not. It is
possible to disable automatic detection of
CMAKE_CXX_STDLIB_MODULE_JSON by setting it to the empty string.
When available, the CMAKE_CXX_STDLIB_MODULE_JSON will be used to create
all requested C++ stdlibs which do not already have targets.
Extend commit e6aa7742b0 (VS: Generate .slnx files for VS 2026,
2025-09-17, v4.2.0-rc1~151^2) to add the `Type=` attribute on SLNX
`<Project>` elements.

At the time of commit e6aa7742b0 (VS: Generate .slnx files for VS 2026,
2025-09-17, v4.2.0-rc1~151^2), the VS 18 Insiders edition did not offer
support for specifying a default startup project in `.slnx` files.
This has since been added, so use it.
Fixes: #27387
Extend commit 7f15c99851 (CUDA: forward unknown flags to host compiler
when possible, 2019-11-29, v3.17.0-rc1~326^2~1) to work in VS too.
Fixes: #27210
In commit b1b3602cda (FASTBuild: remove non-existent autogen byproducts,
2025-11-10) we added an unnecessary nullptr check on a pointer we know
to be non-nullptr. Since then, `clang-analyzer` takes that check as a
hint that the pointer might be nullptr, and has reported missing nullptr
checks elsewhere.

QStandardItemModel::beginResetModel() and
QStandardItemModel::endResetModel() calls cannot be nested, and Qt will
produce warnings at runtime if such nesting is detected.
The nesting happened in two places:
1. QCMakeCacheModel::setViewType calls QCMakeCacheModel::setProperties.
Both called beginResetModel.
2. QCMakeCacheModel::setProperties calls QStandardItemModel::clear(),
which also calls beginResetModel.
The fix for 1 is to remove the {begin|end}ResetModel calls from
setViewType. The setProperties calls take care of the
{begin|end}ResetModel calls.
The fix for 2 is to replace the clear() call with a call that removes
all data rows.
Issue: #27376
`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.

Print the system error message in case of failure when calling
`CopyFileAlways`, `CopyFileIfDifferent`, `CopyFileIfNewer`,
`CopyADirectory` and `MakeDirectory`.
Remove unnecessary `cmSystemTools` wrappers for `CopyFileIfNewer` and
`CopyADirectory`.
