Genex: Teach SHELL_PATH to support a list of paths

Browse Source 
Extend the genex added by commit ca6ba3fee5 (Genex: Add a SHELL_PATH
expression, 2015-09-24, v3.4.0-rc1~37^2) to accept a `;`-list of paths,
convert them all, and generate a list separated by the native shell
`PATH``` separator.

Content of ``...`` converted to shell path style. For example, slashes are
converted to backslashes in Windows shells and drive letters are converted
to posix paths in MSYS shells. The ``...`` must be an absolute path.
The ``...`` may be a :ref:`semicolon-separated list <CMake Language Lists>`
of paths, in which case each path is converted individually and a result
list is generated using the shell path separator (``:`` on POSIX and
``;`` on Windows). Be sure to enclose the argument containing this genex
in double quotes in CMake source code so that ``;`` does not split arguments.
