Message:

Site Health: Include new tests to check for the ability to upload files.

Several new checks:

• max_file_uploads
• file_uploads
• post_max_size
• upload_max_filesize
• upload_max
• max_file_uploads

In addition, new function parse_ini_size() that converts shorthand byte strings to bytes. Useful for size comparisons.

Fixes #50038.
