fix(windows): handle invalid package names during install

Fixes #4886.

This patch includes 5 separate fixes for the various scenarios we
encountered during package installation.

1. RunTools.pas: don't attempt to install TIPs if package is not also
   being installed.

2. Keyman.Setup.System.OnlineResourceCheck.pas, OnlineUpdateCheck.pas:
   handle online update check for packages with spaces or periods in the
   id (legacy packages only).

3. Keyman.Setup.System.InstallInfo.pas: Handle browsers renaming
   downloaded files with `(n)` and `[n]` patterns as well as the current
   ` (n)` pattern.

4. Keyman.Setup.System.InstallInfo.pas: Handle browsers renaming
   downloaded files with `_n` pattern. See code comments for details.

5. Keyman.Configuration.System.TIPMaintenance.pas: Avoid crashing if
   `kmshell -install-tips-for-packages` is passed an invalid package
   name.

The crash is actually fixed in point 5 above, but the root causes are
addressed in the other points.
