[boost-gil] remove dependency boost-filesystem (#20575)

* [boost-gil] remove dependency boost-filesystem
This dependency is optional and only used to build and run tests and examples.
See https://github.com/boostorg/gil#requirements
However, there is also BOOST_GIL_IO_ADD_FS_PATH_SUPPORT which enables
boost::filesystem::path support for IO functions, but since users have to define
it manually, they must install the dependency manually, too.

* fix spacing

* fix generate-ports.ps1
