SCons: Do not enable werror=yes by default

Browse Source 
There are too many users who compile Godot from source and are not familiar
with the buildsystem or C/C++ compilation warnings, and thus report any kind
of yet-unfixed warning as a (often duplicate) bug.

Compiler warnings change at every compiler version and are different for each
compiler, so it's difficult to ensure that the codebase would always be 100%
warning-free, especially in the future.

I already disabled it for stable releases in #37958, but having it on non
stable commits could also become an annoyance in the future when trying to
bisect issues with a new compiler version which emits warnings unknown at
the time of commit.

TL;DR: Contributors, use `dev=yes` or `werror=yes`. CI does and won't let you
create new warnings ;)
