examples: remove auto-generation of examples list

examples: remove auto-generation of examples list

The examples/meson.build file scanned the filesystem to find all examples
to build (for examples=all option) and install. However, using run_command
and scanning the filesystem prevented ninja from properly detecting the
addition or removal of any examples - one had to recreate the build
directory from scratch to guarantee correct detection of all examples. This
patch replaces this generated list with a static list of examples, thereby
allowing proper tracking by ninja/meson, but at the cost of having to
update this file when a new example is added or removed.

This also fixes an issue with Windows builds, since "sh" is not available
there.
