It turns out that most V3D versions change very few packets, so keeping
separate copies of the XML per version makes changing the XML a pain as
you have to replicate your changes to each one. This is the start of
changing it so that one XML can generate headers for multiple versions.
Since commit 7f80a9ff13 ("vc4: Introduce XML-based packet header
generation like Intel's."), the vc4 build on Android is broken:
out/target/product/linaro_x86_64/gen/STATIC_LIBRARIES/libmesa_broadcom_genxml_intermediates/broadcom/cle/v3d_packet_v21_pack.h:12:10: fatal error: 'v3d_packet_helpers.h' file not found
external/mesa3d/src/gallium/drivers/vc4/vc4_cl_dump.c:28:10: fatal error: 'vc4_packet.h' file not found
The path of the generated header needs to be fixed since we build out of
tree.

I really liked this idea, as it should help with management of packet
parsing tools like the CL dump. The python script is forked off of theirs
because our packets are byte-based instead of dwords, and the changes to
do so while avoiding performance regressions due to unaligned accesses
were quite invasive.
v2: Fix Android.mk paths, drop shebang for python script, fix overlap
detection.
