This patch factors out the "VLMax" operand passed to most
scalable-vector ISel patterns into a property of each VType.

This is seen as a preparatory change to allow RVV in the future to
more easily support fixed-length vector types with constrained vector
lengths, with the AVL operand set to the length of the fixed-length
vector. It has no effect on the scalable code generation path.
