environment: move trust_executable_bit into repo_config_values
Move the global 'trust_executable_bit' configuration into the repository-specific 'repo_config_values' struct. To ensure code readability, the getter function 'repo_trust_executable_bit()' has been introduced. Callers access this configuration by passing in 'repo' when possible, and explicitly fall back to 'the_repository' the rest of time.
