[dev.fuzz] internal/fuzz: allow float types to be integer literals
Previously, something like `float64(0)` would fail to decode
since the 0 value is considered an integer literal, and the
float64 parsing code required a float literal. Be more flexible
here since an integer can always be converted to a float.
