[Ada] Optimize nonstandard boolean validity checking
Validity checking of enumerations with nonstandard representation
starts by checking the value range, then calling _rep_to_pos to verify
that the value itself is valid. The value range check is thus
redundant and inefficient: the _rep_to_pos call is normally inlined
when optimizing for speed and the range check slows down the fast
path; it is unnecesary and undesirable when optimizing for size, and
just unnecessary when not optimizing. This patch thus drops the range
check for nonstandard boolean types.

Drop redundant range check for nonstandard booleans.
