Reduce pac solution noise

[filcole]

pac will often output multiple lines rather than updating the existing line, e.g. for execution time and percentage complete. This happens mainly in the solution and deploy suite of commands. It would be good to remove the noise here. Some options:

1. Remove the blank lines between updates - so doesn't scroll off the top as quick
2. Remove percentage complete (because it doesn't ever reach 100%) and just show execution time
3. When running interactively, update the same line on the terminal, rather than outputting a new line. In a similar behaviour to npm install or winget

Example:
