packaging: ship DBC source files and runtime data in the wheel (#3349)

* packaging: ship DBC source files and runtime data in the wheel

The 0.3.0 wheel only shipped safety headers via package-data. Every other
data file (.dbc, .capnp, .toml, CARS_template.md) was missing, which meant
the published package couldn't load any DBC or initialize car interfaces
out of the box.

Declare explicit package-data patterns for opendbc.dbc and opendbc.car so
the generator's source .dbc files, rlog.capnp, the torque_data TOMLs, and
the docs template are all included.

After this, a clean \`pip install opendbc\` successfully round-trips a CAN
message through CANPacker + CANParser.
