Missing CommandBuffer overloads

[Tearnote]

Most CommandBuffer member functions, like bind_buffer, can take either a Buffer or a Name. Some of them though, like bind_index_buffer or draw_indexed_indirect, take only a Buffer, and that needs to be worked around with the verbose *cmd.get_resource_buffer("bufferName"). Would be nice to have full feature parity for names here.

Fixed in 62589e0 - please reopen if there is still some missing.
