This commit enables `/std:c++20` for local development under VS17.
Our CIs will continue to use VS16 and C++17 for now in order to reduce
the likelihood of regressions during the current development cycle.
It's expected that we'll migrate to VS17 soon, as this
is what conhost is already being built with anyways.

## Detailed Description of the Pull Request / Additional comments
🛑 **STOP** 🛑 - have you read #3495 yet? If you haven't, go do that now.
This PR adds support for three initial sub-commands to the `wt.exe` application:
* `new-tab`: Used to create a new tab.
* `split-pane`: Used to create a new split.
* `focus-tab`: Moves focus to another tab.
These commands are largely POC to prove that the commandlines work. They're not totally finished, but they work well enough. Follow up work items will be filed to track adding support for additional parameters and subcommands
Important scenarios added:
* `wt -d .`: Open a new wt instance in the current working directory #878
* `wt -p <profile name>`: Create a wt instance running the given profile, to unblock #576, #1357, #2339
* `wt ; new-tab ; split-pane -V`: Launch the terminal with multiple tabs, splits, to unblock #756
## Validation Steps Performed
* Ran tests
* Played with it a bunch
