pkgconfig: add support for pkgconfig generation for c#

this adds support for generating pkgconfig files for c#.

The difference to c and cpp is that the -I flag is not known to the c#
compiler, but rather the -r flag which is used to link a .dll file into
the compiled library.

However this opens the question of validating which pkgconfig files can
be generated (depending on the language).

This implements 4409.
