Under Windows, strip paths of any `\\?\` prefix to prevent Duplicati
from storing paths prefixed with `\\?\`.
This fixes an inconsistency in the stored data where, if the user
provided a prefixed path to back up (e.g., `\\?\C:\Temp`), Duplicati
would store an entry with the prefixed path (e.g., `\\?\C:\Temp`)
along with entries with paths stripped of their prefix (e.g.,
`C:\Temp\file.txt`). By only storing non-prefixed paths, this also
avoids an error reported by the GUI when it would encounter a prefixed
path:
```
Filter for list-folder-contents must be a path prefix with no wildcards Parameter name: filter
```
Add comment in `WindowsSnapshot.ConvertToSnapshotPath()` warning how
replacing some manual path construction code with Path.Combine() alone
can lead to invalid snapshot paths.
Revert the change made to `WindowsSnapshot.ConvertToSnapshotPath()`
by pull request #4256.
The change in #4256 replaced some existing manual path construction
code with a call to `SystemIO.IO_WIN.PathCombine()`, but calling
`SystemIO.IO_WIN.PathCombine()` this way did not always result in
valid VSS paths. For example, trying to back up a root volume like
"C:\" would result in the following error:
```
The filename, directory name, or volume label syntax is incorrect.
```
This updates all projects to target .NET Framework 4.7.1. The
TencentCOS and Tardigrade backends depend on .NET Standard 2.0. When a
.NET Framework prior to 4.7.1 is targeted, the system cannot be sure
that all the dependencies exist, so it copies all dependent assemblies
to the output directory. This causes many assemblies from the System
namespace to become bundled in the release.

We had previously attempted to make individual projects target 4.7.1
(see pull request #4242), but this can cause compatibility issues when
4.6.2 projects depend on 4.7.1. projects.
This will require Mono 5.10.0 or greater (previously, we required 5.0.0
or greater).

This fixes issue #4234.
Fix pull request string comparisons in SystemIOWindows.cs to use
StringComparison.Ordinal.
Fix pull request to use SystemIO.IO_WIN.PathCombine() in
WindowsSnapshot.cs.
Allow historically problematic Windows paths (i.e., files or
directories that end in a dot or a space) to be backed up with
Duplicati in Windows.
This fixes#3839.
