Introduces a new TerminalSettingsModel (TSM) project. This project is
responsible for (de)serializing and exposing Windows Terminal's settings
as WinRT objects.

In the process of ripping out TSM from TerminalApp, a few other changes
were made to make this possible:
1. AppLogic's `ApplicationDisplayName` and `ApplicationVersion` was
moved to `CascadiaSettings`
- These are defined as static functions. They also no longer check if
`AppLogic::Current()` is nullptr.
2. `enum LaunchMode` was moved from TerminalApp to TSM
3. `AzureConnectionType` and `TelnetConnectionType` were moved from the
profile generators to their respective TerminalConnections
4. CascadiaSettings' `SettingsPath` and `DefaultSettingsPath` are
exposed as `hstring` instead of `std::filesystem::path`
5. `Command::ExpandCommands()` was exposed via the IDL
- This required some of the warnings to be saved to an `IVector`
instead of `std::vector`, among some other small changes.
6. The localization resources had to be split into two halves.
- Resource file linked in init.cpp. Verified at runtime thanks to the
StaticResourceLoader.
7. Added constructors to some `ActionArgs`
8. Utils.h/cpp were moved to `cascadia/inc`. `JsonKey()` was moved to
`JsonUtils`. Both TermApp and TSM need access to Utils.h/cpp.
A large amount of work includes moving to the new namespace
(`TerminalApp` --> `Microsoft::Terminal::Settings::Model`).
Fixing the tests had its own complications. Testing required us to split
up TSM into a DLL and LIB, similar to TermApp. Discussion on creating a
non-local test variant can be found in #7743.
Closes#885

## Detailed Description of the Pull Request / Additional comments
## Validation Steps Performed
Added the following keybindings:
```json
{ "keys": "p", "command": { "action": "sendInput", "input": "foobar" } },
{ "keys": "q", "command": { "action": "sendInput", "input": "\u001b[A" } },
```
Ensured that when pressing <kbd>P</kbd> "foobar" is echoed to the shell and when pressing <kbd>Q</kbd> the shell history is being navigated backwards.
This commit adds a debugging feature that can be activated by holding
down Left Alt _and_ Right Alt when a new tab is being created, if you
have the global setting "debugFeatures" set to true. That global setting
will default to true in DEBUG builds.
That debugging feature takes the form of a split pane that shows the raw
VT sequences being written to and received from the connection.
When those buttons are held down, every connection that's created as
part of a new tab is wrapped and split into _two_ connections: one to
capture input (and stand in for the main connection) and one to capture
output (and be displayed off to the side)
Closes#3206
