Update `.clang-format` with configuration to make the 6.0 format as
close as possible to what 3.8 produced before. Then revise the style:
* Indent preprocessor directives (a feature new since 3.8)
* Add a newline and indentation before inheritance `:` and `,`
Rename the Git attribute identifying the format to include the
clang-format version number: `format.clang-format-6.0`. This will aid
external infrastructure in knowing what version of the tool to run.
The `crlf` attribute is deprecated in Git. This also changes the given
files to be in the index using LF newlines, but they will be checked
out with CRLF newlines due to the attribute.
* Add AppContainerApplication to non-UTILITY targets
* Generate app manifest and related files if project does not provide them.
Place them in a per-target directory to avoid clashes.
* Mark WinRT components with WinMDAssembly
* Import Windows Phone 8.0 targets in .vcxproj files when necessary,
and reference platform.winmd.

Teach the Windows-GNU.cmake platform file to look for Visual Studio
tools matching the target ABI. Add an extra step to the link command
for shared libraries and executables that export symbols and on which a
new GNUtoMS property is set (initialized by the CMAKE_GNUtoMS option).
Tell the GNU linker to output a module definition (.def) file listing
exported symbols in addition to the GNU-format import library (.dll.a).
Pass the .def file to the MS "lib" tool to construct a MS-format DLL
import library (.lib).
Teach the install(TARGETS) command to install the MS import library next
to the GNU one. Teach the install(EXPORT) and export() command to set
the IMPORTED_IMPLIB property pointing at the import library to use the
import library matching the tools in the importing project.
