Remove our custom declarations for cpp_std=c++11 and -Werror, instead
prefering to use the built-in default_option parameters from meson.

Our custom compiler flags (such as -Wno-unused-parameter) are
maintained.

I think warning_level=2 adds -Wextra, and all warning levels include -Wall for 
both clang and gcc.

Apart from that,
