[PATCH v7 8/9] environment: move autorebase into repo_config_values

[Tian Yuchen <cat@malon.dev>]

The global variable 'autorebase' dictates whether a newly created
branch should be configured to automatically rebase by default.
Move it into 'struct repo_config_values' to continue the
libification effort.

The 'enum rebase_setup_type' definition is moved higher up in
'environment.h' so that it is visible to the repository-specific
structure. The default state AUTOREBASE_NEVER is now correctly
initialized in 'repo_config_values_init()'.

Configuration parsing in 'git_default_branch_config()' is updated to
write directly to the repository's configuration instance.
