Increase System.IO.FileSystem test coverage

[adamsitnik]

We need tests for:

• [x] reading from and writing to files located on a remote machine (#54474 and #54475, added in #54545)
• [x] reading from and writing to files located on a device (#54143, added in #54545 and #54673)
• [ ] using more file systems:
  • [ ] Windows NFS server (#44546)
  • [ ] delayed allocations like ext4 from #32600
  • [ ] different max file size like FAT32 (#66544) (test)
  • [ ] probably much more than the three above
• [ ] writing to a disk that becomes full (#38742)

@Jozkee @stephentoub @carlossanlop PTAL at the list and feel free to add something. I would really love to extend our test coverage in .NET 7.

• Writing to a remote disk that becomes full (we currently have a manual test, not sure if this could be automated).
• Explicitly get results for different filesystems: NTFS, FAT32, EXT4, APFS, etc.
