Fix fast clicks on File Browser sort columns not changing sorting

Clicking on the column header is supposed to enable sorting by this
column, or switch the sort order if already enabled.
The double-click event would be blocked by the `file.execute()`
operator, which is not supposed to act if the user clicked outside the
file list.

Fix T79616: Sort by column in filebrowser is broken

After changes in rBc606044157a3, mouse press events would be blocked by
the selection operator. This only worked by chance before.

Merge branch 'blender-v2.90-release' into master

Code Style: use "#pragma once" in intern/ghost

More information can be found in D8466.

Code Style: use "#pragma once" in some newer headers

Those were missing from the previous commit, because these headers
only exist in the `master` and not in the `blender-v2.90-release` branch.

Cleanup: make format

Merge branch 'blender-v2.90-release' into master

Code Style: use "#pragma once" in source directory

This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.

This patch has been generated by P1561 followed by `make format`.
