scons: Disable some warnings in clang.

The defaulted-function-deleted warning triggers in generated code which
would be very tricky to address.

The c99-designator refers to using an array index to specify which
element of an array is being initialized. This makes the code more
clear and is supported by both g++ and clang++. Designated initializers
for structures are being introduced in C++20, but there is no word I
could find on arrays. This warning option seems to only exist in clang
versions 10 and up, so we can only use it on those versions.
