Fixes #59320

Switches webview scrollbars to use themecolors instead of hardcoded values

Fixes #60960

Adds two fixes for  #60960

- Don't convert uris to strings for serialization but instead leave them as their components. This lets us avoid having to call `parse` in `deserialize`

- Add try catches around operations like `parse` that may throw

Add typings for the pattern: `let x = []` which defaults to `let x: any[] = []`

#60565

Most converters are already using namespaces. Switch a few using const object to use namespaces instead

Fixes #61141

fixes #61126

Adds a new setting: `terminal.integrated.splitCwd`
With these options: `workspaceRoot`, `sourceInitialCwd`, `sourceCwd`
`workspaceRoot`is the existing behavior. The new split terminal's cwd will be the workspace root.
`sourceInitialCwd` uses the 'parent' terminals initial cwd for the new terminal.
`sourceCwd` on macOS and Linux this gets the cwd of the 'parent' terminal and uses that as the cwd for the new split terminal.
Default setting is to keep the existing behavior with `workspaceRoot`
