  [mlir][tosa] Fix select folder when operands are broadcast (#165481)

This commit addresses a crash in the dialects folder. The currently
folder assumes no broadcasting of the input operand happens and
therefore the folder can complain that the returned value was not the
same
shape as the result.

For now, this commit ensures no folding happens when broadcasting is
involved. In the future, folding with a broadcast could likely be
supported by inserting a `tosa.tile` operation before returning the
operand. This type of transformation is likely better suited for a
canonicalization pass. This commit only aims to avoid the crash.
