percent_decompiled: Add split percentages

[riptl]

Adds a new "code (split)" column to percent_decompiled.

The new output looks like this:

--------------------------------------------------

Player:
 - 5463 BR (main.dol)
 - 5000 VR (StaticR.rel)
1 BR = 118.0 lines of asm code.
1 VR = 183.3 lines of asm code.

Also now rendering table to HTML.
To facilitate this, the graphic.py CI job was moved into the Linux/Wine build.
