Windows: Embed an application manifest in the EXE files

Windows: Embed an application manifest in the EXE files

IMPORTANT: This includes a security fix to command line tool
           argument handling.

Some toolchains embed an application manifest by default to declare
UAC-compliance. Some also declare compatibility with Vista/8/8.1/10/11
to let the app access features newer than those of Vista.

We want all the above but also two more things:

  - Declare that the app is long path aware to support paths longer
    than 259 characters (this may also require a registry change).

  - Force the code page to UTF-8. This allows the command line tools
    to access files whose names contain characters that don't exist
    in the current legacy code page (except unpaired surrogates).
    The UTF-8 code page also fixes security issues in command line
    argument handling which can be exploited with malicious filenames.

Thanks to Orange Tsai and splitline from DEVCORE Research Team
for discovering this issue.

Thanks to Vijay Sarvepalli for reporting the issue to me.

Thanks to Kelvin Lee for testing with MSVC and helping with
the required build system fixes.
