[IR] Add vscale_range IR function attribute This attribute represents the minimum and maximum values vscale can take. For now this attribute is not hooked up to anything during codegen, this will be added in the future when such codegen is considered stable. Additionally hook up the -msve-vector-bits=<x> clang option to emit this attribute. Differential Revision: https://reviews.llvm.org/D98030

[IR] Remove unbounded as possible value for vscale_range minimum The default for min is changed to 1. The behaviour of -mvscale-{min,max} in Clang is also changed such that 16 is the max vscale when targeting SVE and no max is specified.
