[15/21] builtin/config: convert `value_pattern` to a local variable

Commit Message

Patrick Steinhardt May 10, 2024, 11:25 a.m. UTC

The `value_pattern` variable is used by the `format_config()` callback
when `CONFIG_FLAGS_FIXED_VALUE` is used. It is only ever set up by its
only caller, `collect_config()` and can thus easily be moved into the
`collect_config_data` structure.

Do so to remove our reliance on global state.
