Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.
Fixes: #19491
Set the MinTypeNameLength option to an impossibly high value in order
to limit the diagnostics to iterators. Leave new expressions and cast
expressions for later.

This replaces invocations of
- `cmSystemTools::IsInternallyOn` with `cmIsInternallyOn`
- `cmSystemTools::IsNOTFOUND` with `cmIsNOTFOUND`
- `cmSystemTools::IsOn` with `cmIsOn`
- `cmSystemTools::IsOff` with `cmIsOff`
- Removes `cmDefinitions::Set` method overload that takes a `const char*`
value argument.
- Updates calls to `cmDefinitions::Set` to use the `cm::string_view` based
version instead.
In `cmState::GetGlobalProperty` we use a macro to produce a string of
the form ";a;b;c" and want to return "a;b;c" by skipping the leading
";". Switch from pointer arithmetic to indexing+addressing to silence
the "warning: adding 'int' to a string does not append to the string"
diagnostic from Clang.

-- Forward GHS platform variables to try_compile()
CMAKE_TRY_COMPILE_PLATFORM_VARIABLES only worked for source signature try_compile()
-- Update tests to no longer add GHS platform variables to try_compile()
-- Avoid linker error in GhsMulti/GhsMultiCompilerOptions/CMakeLists.txt by building library
Since commit v3.10.0-rc1~391^2~3 (Add directory property 'LABELS' and
CMAKE_DIRECTORY_LABELS variable, 2017-06-23) this command was
accidentally not allowed in script mode. It was dropped because
`ctest -S` mode needs to start with CMake's normal script mode and
then replace the `set_directory_properties` implementation. Restore
the normal `set_directory_properties` in script mode and then add
special logic to replace it in ctest. Also add a test case.

These new capabilities enable to manage link directories
Two new properties:
* target properties: LINK_DIRECTORIES and INTERFACE_LINK_DIRECTORIES
One new command
* target_link_directories(): to populate target properties
Fixes: #17215
This family enable to manage link flags
Three new properties:
* directory property: LINK_OPTIONS
* target properties: LINK_OPTIONS and INTERFACE_LINK_OPTIONS
Two new commands
* add_link_options(): to populate directory property
* target_link_options(): to populate target properties
Fixes: #16543
Store both the as-written and lower-case command names and use
the latter to avoid case-insensitive string comparisons.
With this I obtain 2-6% speed increase (on Windows) for the configure
step with no significant changes in memory usage. A case-insensitive
comparison is a lot slower than just calling `==` because the operator
will use things like memcmp, so prefer the latter.
The `cmSystemTools::LowerCase` function allocates a new string each time
it is called, so before this change we were allocating in:
* cmMakefile::Configure two times for each function
(to look for `cmake_minimum_required` and `project`)
* cmMakefile::ExecuteCommand twice by function by calling
cmState::GetCommand and copying the name
Now we are only allocating once by function instead of four.
* Change some functions to take `std::string` instead of
`const char*` in the following classes: `cmMakeFile`, `cmake`,
`cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator`
and a few others.
* Greatly reduce using of `const char*` overloads for
`cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`.
* Remove many redundant `c_str()` conversions throughout the code.
