  [mlir][tosa] Fix integer-to-boolean cast folder (#150370)

According to the TOSA spec, casting to boolean should produce true if
the input is non-zero, and false otherwise — i.e., `out = (in != 0) ?
true : false`. Previous behavior incorrectly relied on truncation, which
could yield incorrect results for non-zero values whose least
significant bit is zero. Fixes #150302.
