SCons: Explicitly define our C (C11) and C++ (C++14) standards

Browse Source 
On GCC and Clang, we use C11 and C++14 with GNU extensions (`std=gnu11`
and `std=gnu++14`). Those are the defaults for current GCC and Clang,
and also match the feature sets we want to use in Godot.

On MSVC, we require C++14 support explicitly with `/std:c++14`, and
make it strict with the use of `/permissive-` (so features of C++17 or
later can't be used).

Moves the definition before querying environment flags and platform
config so that it can be overridden when necessary.
