  -----------
  [mlir][tosa] Remove `log(exp(x))` and `exp(log(x))` folders (#156434)

Both of the folders would reduce to `x`. These folders were vulnerable
to overflow / underflow issues, resulting in a difference in numerical
behaviour when running or not running the folders. For now they have
been removed. We can consider restoring these as part of an optional and
separate "fast-math" style of transformation in the future.
