  [mlir] Optimize const values AffineMap::compose (#141005)

The original implementation will create two intermediate AffineMap in
the context, calling this compose function with different values
multiple times will occupy a lot of memory.

To improve the performance, we can call the AffineExpr::replace
directly, so we don't need to store all combinations of values in the
context.
