VS 2017 version 15.8 introduced support for unity builds implemented
in part by the `$(VCTargetsPath)/Microsoft.Cpp.Unity.targets` file.
Do not enable unity builds on VS 15 versions that do not have that file.
Fixes: #20284
Extend the fix from commit 0578239d3a (VS: Tell VS 16.4 not to verify
SYMBOLIC custom command outputs, 2019-09-23, v3.15.4~2^2) to apply to
SYMBOLIC *inputs* too. This is needed when there is a chain of custom
commands that use symbolic paths for ordering.

Replace our hard-coded default of cudart=static with a first-class abstraction to select the runtime library from an enumeration of logical names.
Original behaviour would unconditionally enable WinRT for all projects
so source file flag generation code can acknowledge WinRT being present
and disable it for C language source files. An unintentional result of
that approach is that WinRT is enabled for ALL projects, including C++
projects/source files with no way to disable it
Instead use `CMAKE_VS_WINRT_BY_DEFAULT` as a hint that the platform is
WinRT-by-default and set global `CompileAsWinRT` flag to `false` unless
it was explicitly requested by either `WINRT_COMPONENT` option or `/ZW`
compilation option - similar to what Windows Phone/Windows Store
platform logic does
In case WinRT compilation is enabled for a project by either of
aforementioned methods, C language source file override logic will still
kick in and disable CompileAsWinRT for C source files
Fixes: #20063
The unity build sources need to be added for all generators. Create
them during `cmGlobalGenerator::Compute` to avoid duplicating the calls
in every generator. We already handle Qt autogen there too.

VS 16.4 introduces an additional check on `CustomBuild` rules that warns
if the outputs of the command are not created. However, CMake supports
marking outputs with the `SYMBOLIC` property to indicate that they will
not actually be generated. That property is used by Makefile and Ninja
generators but has not been needed by the VS generators before. Teach
the VS generator to disable `VerifyInputsAndOutputsExist` in custom
build rules that have a symbolic output.

cmGeneratorExpression::Evaluate is a shortcut when only the evaluated string is
needed or an instance of cmCompiledGeneratorExpression cannot be cached.
Fixes: #19686
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
Our logic that sets `ReferenceOutputAssembly` in `ProjectReference` has
accumulated a series of conditions for different cases in which the
referenced target has no output. Simplify the condition to check
`GetManagedType` directly for cases with no output.
This will explicitly turn off `ReferenceOutputAssembly` in
`ProjectReference` for utility (i.e. `add_custom_target`) and special
targets (i.e. `ZERO_CHECK`, etc.), and allowing reference of target
dependencies that produce some output.
Fixes: #19665
Previously the CMake didn't compute the required set of libraries
needed to properly device link a static library when
CUDA_RESOLVE_DEVICE_SYMBOLS was enabled.

It works as expected in Visual Studio.
Visual Studio 2017 will (partially) benefit from the build in
support for unity builds. The custom unity sources are used, because
the build in support doesn't allow batching of certain number of
files. It can do only batching by directory.
Generator expressions in target property VS_CONFIGURATION_TYPE might be used to
set the ConfigurationType to Utility for certain configurations to not build
the target while still linking to the target in other configurations.
Fixes: #19613
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
