Add MUSIC and VIDEOS players

- Add new video player (based on mpv 0.32.0)
- Add new music player (based on mpv 0.32.0) + fix ffmpeg libretro core
- Add script to extract music covers for MainUI
- Add script to generate playlist from a music subfolder
- New icons created for these players

Notes :
music player supports playlists, wav, mp3, flac ,ogg,m3u...
added a kind of visual equalizer, credits : https://blog.fraggod.net/2018/04/12/mpv-audio-visualization.html
Libretro ffmpeg cores is slow for videos, the visual for music is fun (but in low resolution)
mpv can read 1080p video really well
mpv has been configured to resume video at the same time position
mpv version is a little old (doesn't support lua scripts)
mpv launch scripts use gptokeyb2 to rebind controls into a classical keyboard (credits: PortMaster)

dev remarks:
more keys could be mapped to control mpv
an updated version could bring some nice feature thanks to lua scripts
Controls :
A/B/Start = play pause
up_down = seek 1 minute forward
down_down = seek 1 minute backward
left = seek 5 seconds backward
right = seek 5 seconds forward
l1/r1 = previ / next track
Menu = exit

+# mpv keybindings
+
+ Location of user-defined bindings: ~/.config/mpv/input.conf
+
+ Lines starting with # are comments. Use SHARP to assign the # key.
+ Copy this file and uncomment and edit the bindings you want to change.
+
+ List of commands and further details: DOCS/man/input.rst
+ List of special keys: --input-keylist
+ Keybindings testing mode: mpv --input-test --force-window --idle
+
+ Use 'ignore' to unbind a key fully (e.g. 'ctrl+a ignore').
+
+ Strings need to be quoted and escaped:
+   KEY show-text "This is a single backslash: \\ and a quote: \" !"
+
+ You can use modifier-key combinations like Shift+Left or Ctrl+Alt+x with
+ the modifiers Shift, Ctrl, Alt and Meta (may not work on the terminal).
+
+ The default keybindings are hardcoded into the mpv binary.
+ You can disable them completely with: --no-input-default-bindings
+
+ Developer note:
+ On compilation, this file is baked into the mpv binary, and all lines are
+ uncommented (unless '#' is followed by a space) - thus this file defines the
+ default key bindings.
+
+ If this is enabled, treat all the following bindings as default.
