  [mlir][tosa] Interpret boolean values correctly in cast folder (#147078)

Previously the cast folder would sign extend boolean values, leading
"true" to be casted to a value of -1 instead of 1. This change ensures
i1 values are zero extended, since i1 is used as a boolean value in
TOSA. According to the TOSA spec, the result of a boolean cast with
value "true" to another integer type should give a result of 1.
