panfrost: add dumptex flag to PAN_MESA_DEBUG
The PAN_MESA_DEBUG `dump` flag is advertised to dump all GPU
memory, but in fact it dumps only mapped memory. Textures
typically are not mapped and hence are not included. This is
fine for most use cases, but occasionally we do want to
dump texture memory as well. This patch adds a `dumptex` flag
to dump those when `dump` is enabled.
