This commit fixes the case sensitivity of tool package identifiers.
Previously the install and uninstall commands unintentionally required the tool
package ids to specified in all lowercase for the install / uninstall to work.
Fixes#8682.
This commit implements the `uninstall tool` command.
The `uninstall tool` command is responsible for uninstalling global tools that
are installed with the `install tool` command.
This commit heavily refactors the ToolPackage and ShellShim namespaces to
better support the operations required for the uninstall command.
Several string resources have been updated to be more informative or to correct
oddly structured sentences.
This commit also fixes `--version` on the install command not supporting ranges
and wildcards.
Fixes#8549.
Issue #8485 is partially fixed by this commit (`--prerelease` is not yet
implemented).
