  [mlir][ArmSME] Add arm_sme.streaming_vl operation (#77321)

This operation provides a convenient way to query the streaming vector
length regardless of the streaming mode. This most useful for functions
that call/pass data to streaming functions, but are not streaming
themselves.

Example:
```mlir
%svl_w = arm_sme.streaming_vl <word>
```
