[PATCH 3/5] pretty: introduce `get_user_format()`

["Hariom Verma via GitGitGadget" <gitgitgadget@gmail.com>]

From: Hariom Verma <hariom18599@gmail.com>

In the quest of porting pretty formats to use ref-filters logic,
user_format must need to interact with other functions too.
So, to get user_format, introduced `const char *get_user_format()`.
