The IPO flag logic was added to `AddLanguageFlags` based on my advice.
However, this method should really only be about `CMAKE_<LANG>_FLAGS*`
variables. Move the IPO logic out to its call sites.
The new `cmQtAutogenGlobalInitializer::Keywords` class instance is bound to
the lifetime of the `cmQtAutogenGlobalInitializer` instance. Global static
const strings would be allocated at program start and deallocated at program
end. Keeping keyword strings alive only in the context where they're
needed helps to reduce the memory footprint.

The `cmLocalGenerator::GetIncludeDirectoriesImplicit` method is called
by `cmQtAutoGenInitializer` to get the compiler's list of implicit
include directories. Since commit 557b2d6e65 (Fix regression in
-I/usr/include exclusion logic, 2019-02-13, v3.14.0-rc2~6^2~2) the
method hard-codes exclusion of `/usr/include` for historical reasons.
However, it should not be reported as a real implicit include directory
unless the compiler really has it.
Refactor the logic to distinguish the hard-coded exclusion of
`/usr/include` from the real list of implicit include directories.
Fixes: #19100
In `cmDepends` use
`typedef std::map<std::string, std::vector<std::string>> DependencyMap`
instead of defining a
`class DependencyVector : public std::vector<std::string>`
and using it in `std::map<std::string, DependencyVector>`.
Since `std::map<std::string, std::vector<std::string>>` is used in various
other places, we now reuse all of it's auto generated methods. This doesn't
happen when we use `DependencyVector` in a `std::map`, because it is a
different class than `std::vector<std::string>`.
This patch changes the following issues in `cmDepends::CheckDependencies`:
- Use the `std::string` based `std::getline` interface to read lines from a
file instead of using raw reads into raw buffers.
- To reduce the file system access, we load file times only once from
`cmFileTimeCache` and keep them on the stack for later comparison.
- When a file is removed from the file system we remove it from the
`cmFileTimeCache` as well.
