More statvfs info for mount facts rebase 12073 (#25454)

Browse source 
* Add more mount point statvfs info including sizes

Based on https://github.com/ansible/ansible/pull/12073

facts.utils.get_mount_size() now returns a dict of most
of the posix statvfs data, including block_size and inode
counts.

Update the facts.hardware classes that use get_mount_size() to
use the new info by mount_info.update(mount_statvfs_inof) to merge.

* add back unit tests for LinuxHardware mount/fs facts

* add test cases for facts.utils.get_mount_size
