Compiler Attributes: homogenize __must_be_array
Different definitions of __must_be_array:
* gcc: disabled for __CHECKER__
* clang: same definition as gcc's, but without __CHECKER__
* intel: the comment claims __builtin_types_compatible_p()
is unsupported; but icc seems to support it since 13.0.1
(released in 2012). See https://godbolt.org/z/S0l6QQ
Therefore, we can remove all of them and have a single definition
in compiler.h
