An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
This patch strips the `stripImplicitDirs` and `appendAllImplicitDirs`
parameters from the `cmLocalGenerator::GetIncludeDirectories` method and makes
it a wrapper into the new `cmLocalGenerator::GetIncludeDirectoriesImplicit`
method. `cmLocalGenerator::GetIncludeDirectoriesImplicit` is the renamed old
implementation of `cmLocalGenerator::GetIncludeDirectories` and still
accepts `stripImplicitDirs` and `appendAllImplicitDirs`.
The motivation is that there's only *one* case where
`cmLocalGenerator::GetIncludeDirectories` is called with the
`stripImplicitDirs` parameter being `false` (QtAutoGen), but many other places
where it is called using the `true` default value.
QtAutoGen is modified to use `cmLocalGenerator::GetIncludeDirectoriesImplicit`
directly. In two use cases of `cmLocalGenerator::GetIncludeDirectories`
the manually set `true` value for `stripImplicitDirs` is removed.
Offer clients a `project()`-centric view of the build system. This is
similar to the directory-centric view but consolidates subdirectories
that do not call `project()` with a new project name.
