[cppmicroservices] Add new port (fix #5801)

[saschazelzer]

I tested this port on Windows using

x86-windows
x86-windows-static
x64-windows
x64-windows-static

and Linux (Fedora 29)

x64-linux
x64-linux-static

I do not have access to a Windows ARM platform though.

Hi @saschazelzer, thanks for the new port. I see some failures from the current CI system:

x64-osx	master	test	notes
cppmicroservices		Fail	New Port

arm64-windows	master	test	notes
cppmicroservices		Fail	New Port

x64-uwp	master	test	notes
cppmicroservices		Fail	New Port

arm-uwp	master	test	notes
cppmicroservices		Fail	New Port

Please refer to the following attachment to see what happended on these triplets.

x64-windows-static results are inconclusive because it is missing logs from test
As for x64-windows-static, we get some exception info like this:
