[v10,3/8] t1006: split test utility functions into new "lib-cat-file.sh"

Commit Message

Eric Ju Jan. 14, 2025, 2:14 a.m. UTC

This refactor extracts utility functions from the cat-file's test
script "t1006-cat-file.sh" into a new "lib-cat-file.sh" dedicated
library file. The goal is to improve code reuse and readability,
enabling future tests to leverage these utilities without duplicating
code.
