ref-filter.h: add max_count and omit_empty to ref_format

Browse Source 
Add an internal 'array_opts' struct to 'struct ref_format' containing
formatting options that pertain to the formatting of an entire ref array:
'max_count' and 'omit_empty'. These values are specified by the '--count'
and '--omit-empty' options, respectively, to 'for-each-ref'/'tag'/'branch'.
Storing these values in the 'ref_format' will simplify the consolidation of
ref array formatting logic across builtins in later patches.
