[mlir][ArmSME] Lower extract from 2D scalable create_mask to psel (#96066)
Example:
```mlir
%mask = vector.create_mask %a, %b : vector<[4]x[8]xi1>
%slice = vector.extract %mask[%index]
: vector<[8]xi1> from vector<[4]x[8]xi1>
```
Becomes:
```mlir
%mask_rows = vector.create_mask %a : vector<[4]xi1>
%mask_cols = vector.create_mask %b : vector<[8]xi1>
%slice = arm_sve.psel %mask_cols, %mask_rows[%index]
: vector<[8]xi1>, vector<[4]xi1>
```
Note: While psel is under ArmSVE it requires SME (or SVE 2.1), so this
is currently the most logical place for this lowering.
