Add a one-shot execution mode for .NET tools

Is your feature request related to a problem? Please describe.

Currently to use a .NET global tool that may or may not be installed, you need to perform a series of steps

• install the tool globally
• ensure the global tool install directory is on the PATH
• invoke the tool
• (optionally) remove the tool

And for local tools, you need to

• create a tool manifest
• install the tool
• invoke the tool
• (optionally) remove the tool

When all you really want to do is

• invoke the tool

We should consider adding a mode of running a .NET tool that combines all of these steps into one user-facing step.

Describe the solution you'd like

Something akin to

dotnet toolx [-g|--global] [--rm] [--version toolVersion] <toolName> [tool args and options]

that would combine all of the preceding steps into one logical command. The tool would be installed (locally by default, creating a manifest if necessary), executed passing along whatever args, and then optionally being uninstalled after execution. If a version was supplied and the locally-available version of the tool (if any) doesn't satisfy that version, the specified version would be installed.
