Yong Tang cd3a202f52 Fix one-character directory issue in the volume option (#20122). ...

The issue comes from the implementation of volumeSplitN() where a
driver letter (`[a-zA-Z]:`) was assumed to follow either `:`, `/`,
or `\\`.

In Windows driver letter appears in two situations:
a. `^[a-zA-Z]:` (A colon followed  by `^[a-zA-Z]:` is OK as colon is
the separator in volume option)
b. A string in the format like `\\?\C:\Windows\...` (UNC).
Therefore, a driver letter can only follow either a `:` or `\\`

This PR removes the condition of `/` before the driver letter so
that options like `-v /tmp/q:/foo` could be handled correctly. A
couple of tests has also been added.

This PR fixes #20122.
