Make `BLI_path_contains()` case-insensitive on Windows. This behaviour
is dependent on the platform Blender is running on, like the rest of
BLI_path, and not on the style of paths (Windows-style paths will be
treated case-sensitively when Blender is running on Linux/macOS).
Add function `BLI_path_contains(container, containee)` that returns true
if and only `container` contains `containee`.
Paths are normalised and converted to native path separators before
comparing. Relative paths are *not* made absolute, to simplify the
function call; if this is necessary the caller has to do this conversion
first.
The file was including BKE. It was a required fix for another
compilation error a while back. It is a bad level include, and
seems is not needed anymore.
And make them part of the blender_test runner. The one exception is blenlib
performance tests, which we don't want to run by default. They remain in their
own executable.
