The Makefile supports a target called 'hdr-check', which checks if
individual header files can be independently compiled. Let's port this
functionality to meson, our new build system too.
Let's avoid the abbreviation and name the target 'headers-check', which
is easier to read.
The implementation resembles that of the Makefile and provides the same
check.
