meson: Enable shadowed variable warning

Shadowing variables can lead to unexpected bugs where a code path
utilises a variable that may not have been intended by the developer,
leading to hard to find bugs.

Enable warnings for shadowed variables as defined at:
  https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wshadow

As an effect of utilising -Werror, this will cause variable or type
shadowing to become a build-time error.
