GameDB: internal FPS by DISPFB blit for NASCAR Thunder 2002 through NASCAR 06

Browse Source 
The register-write detector reads these engines as producing a new image every
vblank, so duplicate-frame skipping never fires and every repeat pays for a full
present. Counting blits into the displayed framebuffer restores it.

# NASCAR Thunder 2002 through NASCAR 06 — count DISPFB blits instead of
# privileged register writes when working out the internal frame rate. Reported
# by yuasasa on Android handhelds.
#
# The register-write detector reads these engines as producing a new image every
# vblank. SkipDuplicateFrames (default on) trusts that answer, so no duplicate is
# ever dropped and every repeated frame still pays for a full present. Counting
# blits into the displayed framebuffer gives the real render rate and lets the
# skip fire again.
#
# Scope is the five titles the reporter named; every serial each was released
# under is listed, since the fix is a property of the engine and not the region.
# The rest of the series is out on his word that it does not need this. NASCAR 07
# is a separate case — upstream GameIndex.yaml already sets the fix on both its
# serials, and restating it here would put its gameFixes list under this overlay's
# clear-then-replace rule, so anything upstream added later would be dropped on
# mobile.
#
# gameFixes only, for that same rule: upstream carries roundSprite on the Thunder
# entries and deinterlace on Total Team Control, and naming gsHWFixes here would
# delete them.
