testbench: topology:check array size mismatch in filewrite component

This patch uses the functionality added by the c9e090ccf3 commit
to check for array size mismatch in components.

Since, the components are in places other than tplg_parser, the
function which checks for the mismatch has been made an external
function from a static one. The function declaration has been
added to the tplg_parser header files, so that the function can
be used by any code which needs array size checks in components.
