[mlir][scf] Extend consumer fusion to multiple tilable users (#111955 )

Before, consumer fusion expects single usage(or others are terminator
op). This patch supports multiple tilable consumers fusion. 
E.g.
```
%0 = scf.for {
  ...
  %p = tiledProducer
  ...
}
%1 = tilableConsumer1 ins(%0 : ...)
%2 = tilableConsumer2 ins(%0 : ...)
```
===>
```
%0:3 = scf.for {
  ...
  %p = tiledProducer
  %1 = tiledConsumer1 ins(%p : ...)
  %2 = tiledConsumer2 ins(%p : ...)
  ...
}
```
The key process is ensuring that the first user of loop 
should not dominate any define of consumer operand(s).
