Export mrb_int_value that converts mrb_float to Fixnum.
...
Or `Float` if `mrb_float` value is too big (or too small) to fit in
`mrb_int`. The `_int_` in `mrb_int_value` means `Integral` module, which
represents integer-like values in mruby.

Recover #to_int; ref #4177
...
We have removed implicit conversion to strings using `to_int`. But some
users still using `to_int` as a typical integer method, i.e. they do
string check by code like: `obj.respond_to?(:to_int)`. So we have
recovered the method.

Remove implicit conversion using to_int method.
...
The ISO standard does not include implicit type conversion using
`to_int`. This implicit conversion often causes vulnerability.
There will be no more attacks like #4120 .
In addition, we have added internal convenience method `__to_int` which
does type check and conversion (from floats).
