The change allows to selectively disable PrecompiledHeaders.
Despite the `$(VCTargetsPath)/1033/cl.xml` contains an empty value for switch,
for effectively turn off setting need to use /Y- option as described on msdn:

Optional spaces and/or tabs are now understood between the '#' character
and the 'cmakedefine'/'cmakedefine01' words. This indentation is
preserved in the output lines.

When encountering an #include "FOO.moc" statement where
FOO.hpp was chosen over FOO.cpp as the moc source, the
FOO.hpp name was not checked against the moc SKIP list.
Although `$(VCTargetsPath)/1033/link.xml` for v140 and v141 toolsets
contains an entry for `LinkControlFlowGuard`, it does not work when used
in a `.vcxproj` file. Drop our link flag table entries for these
toolsets so that the flag will be passed via `AdditionalOptions`.
FindDoxygen generates some files based on the version of Doxygen whose
content will not vary across a project and are therefore a global
resource that can be shared by all calls to `find_package(Doxygen)` and
to `doxygen_add_docs`. We currently use `${PROJECT_BINARY_DIR}` to
reference their location, but this is not stable because `project()`
calls in a subdirectory can change it. Use `${CMAKE_BINARY_DIR}`
instead.

Make the implementation for this compiler more complete.
IAR has multiple C++ modes, historically they were reduced c++ versions
for embedded that gradually improved to the full standard (which can be
reduced again by e.g. disabling rtti and exceptions). The new
implementation picks the best available, but the c++ mode can also be
overridden by defining `CMAKE_IAR_CXX_FLAG`.
Add C/C++ standard flags so that all modes up to and including the last
supported standard are defined.
Fixes: #16826
Compilers such as MSVC and IAR may have variants that target different
architectures. We have been using a `MSVC_<LANG>_ARCHITECTURE_ID`
variable to hold this information for MSVC. Add an alternative with a
more general name (later we can port MSVC to it too).
This additional information may be needed to generate proper invocations
of the compiler based on its architecture variant.
When `<LANG>_STANDARD` is not set we will not add any language standard
flags. If `<LANG>_EXTENSIONS` is not OFF then our default is supposed
to be ON. In order to support compilers that do not enable their
extensions by default, check a `CMAKE_<LANG>_EXTENSION_COMPILE_OPTION`
variable for an extensions flag to use without any language standard.

When calculating Object Library paths take a look at the
`XCODE_EMIT_EFFECTIVE_PLATFORM_NAME` property to enable builds with
different SDKs. Otherwise a hard-coded architecture could be chosen.

While some features require external Unix tools the
generator is mostly portable.
By enabling it on Windows it can be used for cross platform
packaging.
When VS 2015 was first released, its new v140 toolset came with a
`link.xml` file that changed the `GenerateDebugInformation` boolean
(`false` and `true`) value from earlier toolsets to an enumeration
consisting of the possible values `No`, `Debug`, and `DebugFastLink`.
We first adapted to this in commit v3.4.2~2^2 (VS: Fix VS 2015 .vcxproj
file value for GenerateDebugInformation, 2016-01-08), but that broke
older toolsets that still expected the boolean. Then commit
v3.6.0-rc1~295^2~1 (VS: Fix VS 2015 .vcxproj debug setting for older
toolsets, 2016-02-24) added a hack to fix up the value based on the
toolset in use. Several follow-up commits fixed this for more older
toolsets because our flag table was at the time based on the generator
in use rather than the toolset in use.
Since commit v3.8.0-rc1~396^2 (VS: Choose flag map based on the toolset
name, 2016-10-17) we use a flag table based on the toolset, so the fixup
hack should not be needed. We had to keep it around only due to our
default value for GenerateDebugInformation (`false` or `No`) still being
based on the generator instead of the toolset.
A VS 2015 update was released that changed the v140 toolset `link.xml`
file back to using `false` and `true` for the `GenerateDebugInformation`
enumeration variants previously known as `No` and `Debug`. In order to
know which pair to use, we need to parse the `link.xml` file for the
current toolset.
Switch back to using `false` and `true` unconditionally in our
`GenerateDebugInformation` flag table entries and default value. With
that plus the toolset-based flag table, we now get incorrect values for
`GenerateDebugInformation` only when using a v140 toolset from an older
VS 2015 installation. Detect this case by parsing `link.xml` and add
special logic to convert `false` and `true` to `No` and `Debug` to
satisfy the older toolset specification.
