Corentin Wallez e33b0baa08 Revert "MSL writer: make signed int overflow defined behaviour"
This reverts commit e5dbe24e942a32d4077a352b2634ef9acbbb669d.

Reason for revert: Makes the Tint-Dawn roll fails because of
MSL compilation errors on as_type<uint>(-2147483648):
as_type cast from 'long' to 'uint' (aka 'unsigned int') is not allowed
   
as_type<uint>(-2147483647) compiles fine, so this is most
likely because the MSL compiler types the literal as a long
(since without the - it is larger than the max int32).
