Remove convenience constructor functions for vertex and index buffers.

love.graphics.newVertexBuffer and newIndexBuffer don't do enough to justify their existence since love.graphics.newBuffer already covers all buffer creation functionality.

1-based indices in newIndexBuffer versus 0-based indices in newBuffer(..., {index=true}) was also confusing.
