Animation: Add F2 for renaming markers

F2 allows renaming lots of different types of active items, and now it
also works for markers.

Before, Ctrl+M was used, and it's context-sensitive: you often get
"Mirror Keys" instead, when your cursor isn't on the markers region, and
that operator has nothing to do with either renaming or markers.

**What this commit does:**

- Replace Ctrl+M shortcut with F2.
  - Adds the `TOPBAR_PT_name_marker` panel which is implemented similar
    to the global rename panel. This having to press enter twice to
    confirm or escape twice to cancel, which would happen if the
    `marker.rename` operator was called directly.
- Replace usages of `marker.rename` in the UI with `wm.call_panel`.
- To make the Industry Compatible keymap consistent with Blender
  Default, the rename shortcut only works when hovering the markers
  area.
