Bug description

When running the occ setupchecks command after upgrading to v29.0.3, the following errors related to PHP OPcache configuration are encountered:

✗ PHP opcache: The PHP OPcache module is not properly configured. OPcache is not working as it should, opcache_get_status() returns false, please check configuration.
The maximum number of OPcache keys is nearly exceeded. To assure that all scripts can be kept in the cache, it is recommended to apply "opcache.max_accelerated_files" to your PHP configuration with a value higher than "10000".
The OPcache buffer is nearly full. To assure that all scripts can be hold in cache, it is recommended to apply "opcache.memory_consumption" to your PHP configuration with a value higher than "128"..

It appears that the OPcache checks are being performed even when opcache.enable_cli is disabled. Since OPcache is intentionally disabled for CLI calls by default, these checks should be skipped in this context.

Steps to reproduce

Run v29.0.3.
Run the occ setupchecks command.
Observe the OPcache related errors.

Expected behavior

The occ setupchecks command should:

Skip OPcache checks if opcache.enable_cli is disabled. Only perform OPcache checks if opcache.enable_cli is enabled.

Proposed Solution

Check if opcache.enable_cli is enabled: Before running any OPcache checks, the command should first verify whether opcache.enable_cli is enabled.
Skip checks if disabled: If opcache.enable_cli is disabled (which is a reasonable default and production value), the command should not perform any OPcache checks or return related errors.
Perform checks if enabled: If opcache.enable_cli is enabled, the command can run the OPcache checks for debugging and development purposes.
