Add telemetry for settings UI traffic (#19156)

## Summary of the Pull Request
Adds a telemetry provider to the Terminal.Settings.Editor project as
well as new telemetry events to track traffic through the settings UI.
Specifically, the following events were added:
- `NavigatedToPage`: Event emitted when the user navigates to a page in
the settings UI
- Has a `PageId` parameter that includes the identifier of the page that
was navigated to
- (conditionally added when PageId = `page.editColorScheme`)
`SchemeName` parameter tracks the name of the color scheme that's being
edited
   - conditionally added when PageId = `page.extensions`:
- `ExtensionPackageCount`: The number of extension packages displayed
- `ProfilesModifiedCount`: The number of profiles modified by enabled
extensions
- `ProfilesAddedCount`: The number of profiles added by enabled
extensions
- `ColorSchemesAddedCount`: The number of color schemes added by enabled
extensions
   - conditionally added when PageId = `page.extensions.extensionView`:
- `FragmentSource`: The source of the fragment included in this
extension package
- `FragmentCount`: The number of fragments included in this extension
package
      - `Enabled`: The enabled status of the extension
- (conditionally added when PageID = `page.newTabMenu`) if the page is
representing a folder view
   - conditionally added when PageID = `page.profile.*`:
- `IsProfileDefaults`: if the modified profile is the profile.defaults
object
      - `ProfileGuid`: the guid of the profile that was navigated to
      - `ProfileSource`: the source of the profile that was navigated to
- conditionally added when PageID = `page.profile` (aka the base profile
page):
         - `Orphaned`: tracks if the profile was orphaned
         - `Hidden`: tracks if the profile is hidden
- (conditionally added when PageID = `page.profile.appearance`)
`HasBackgroundImage`: `if the profile has a background image defined`
- (conditionally added when PageID = `page.profile.appearance`)
`HasUnfocusedAppearance`: `if the profile has an unfocused appearance
defined`
- `AddNewProfile`: Event emitted when the user adds a new profile
`IsExtensionView` parameter tracks if the page is representing a view of
an extension
- Has a `Type` parameter that represents the type of the creation method
(i.e. empty profile, duplicate)
- `ResetApplicationState`: Event emitted when the user resets their
application state (via the UI)
- `ResetToDefaultSettings`: Event emitted when the user resets their
settings to their default value (via the UI)
- `OpenJson`: Event emitted when the user clicks the Open JSON button in
the settings UI
- Has a `SettingsTarget` parameter that represents the target settings
file (i.e. settings.json vs defaults.json)
- `CreateUnfocusedAppearance`: Event emitted when the user creates an
unfocused appearance for a profile
- `IsProfileDefaults`: if the modified profile is the profile.defaults
object
   - `ProfileGuid`: the guid of the profile that was navigated to
   - `ProfileSource`: the source of the profile that was navigated to
- `DeleteProfile`: Event emitted when the user deletes a profile
- also includes `ProfileGuid`, `ProfileSource`, `Orphaned` from the
`NavigatedToPage` section above

The page ids can be reused later as a serialized reference to the page.
We already use the one for the extensions page for the "new" badge.
