[PATCH v2 0/8] repo_config_values: migrate more globals

[Olamide Caleb Bello <belkid98@gmail.com>]

Overview
========
This series continues the effort to migrate repository-specific global
variables into struct repo_config_values, further reducing global
state and improving repository isolation.

The previous series introduced the infrastructure for storing
repository-dependent configuration in repo_config_values. This series
extends that work by moving additional environment-related globals into
that struct and updating their call sites accordingly.

This helps avoid cross-repository interference when multiple
repositories are used within the same process, and continues preparing
Git for improved library usage and better encapsulation of repository
state.

Changes since v1:
- Dropped "Base series" section as the dependency has been merged.
- Fixed handling of pack_compression_level: removed use of a local copy and
  updated code to operate directly on cfg->pack_compression_level to avoid
  inconsistencies with option parsing.

Olamide Caleb Bello (8):
  environment: move "trust_ctime" into `struct repo_config_values`
  environment: move "check_stat" into `struct repo_config_values`
  environment: move `zlib_compression_level` into repo_config_values
  environment: move "pack_compression_level" into `struct
    repo_config_values`
  environment: move "precomposed_unicode" into `struct
    repo_config_values`
  env: move "core_sparse_checkout_cone" into `struct repo_config_values`
  env: put "sparse_expect_files_outside_of_patterns" in
    `repo_config_values`
  env: move "warn_on_object_refname_ambiguity" into `repo_config_values`
