remove two asserts in int128.nim (#12648) [backport]

Browse source 
Before this PR, `tests/misc/tconv.nim` fails when the compiler
is compiled without `-d:danger` flag.
Bear in mind that even without the asserts, the values outside of
a given range are still checked and a meaningful error message
(from `compiler/semexprs.nim`) is printed.
