VSE: Strip drawing improvements

This patch include changes:
- Thicker and clearer selection indication
- Slimmer handles
- More transparent muted strips
- Trim frame number is drawn inside the strip
- Strip text is drawn in upper part of strip
- Color strips now have specific color, with chosen color drawn under strip text
- Transition strip will use color of input strips showing direction of transition
- Selecting effect strip will highlight input strips
- Selecting multicam strips will highlight target channel
- Missing media state is now indicated by a red line drawn on the top part of the strip
- A checkerboard pattern is now drawn on the outsides of the meta range
- Hold still regions are now always drawn if existent, with a darker shade of the strip’s background color
