[PATCH v2 0/10] MR2993: comdlg32: IFileDialog navigation bar control. Part 1.

[Vladislav Timonin (＠vt)]

Redo of !1857, as suggested, the plan is to split original MR in half, breadcrumbs in first (this) MR, and address edit in another.

The changes are mostly cleanup (formatting, renaming, unused variables, missing free).

Part two branch can be found [here](https://gitlab.winehq.org/vt/wine/-/commits/fd-navbar-part2).

Visually, it hasn't changed:

Requires !2068, otherwise if application doesn't request comctl v6 (e.g. qapitrace), navigation bar will look like this:

![no-comctl-v6](/uploads/03e6a8b6dcf827114157e79640e49fea/no-comctl-v6.png)

- https://bugs.winehq.org/show_bug.cgi?id=54812
- https://bugs.winehq.org/show_bug.cgi?id=50338 (partially? fully with address edit?)
