After making a selection with the Select tool, auto-switch to Move tool

Issue Summary

Related discussion:
https://discuss.pencil2d.org/t/suggestion-implementing-automatic-move-tool-on-bitmap-layers/609

When the user makes a selection with the Select tool, automatically switch to the Move tool so they can edit the picture.

Actual Results

Currently the user has to manually switch to the Move tool every time.

Expected Results

Ideally the program would auto switch to the Move tool for the user.

Steps to reproduce

1. Select the Select tool
2. Use the Select tool to select an area
3. Result: The Select tool is still the active tool, but it should be the Move tool

I'm working on this already

@shieldgenerator7 Hi thank you for this!

There is certainly an issue with the overall select-transform workflow in Pencil2D. From a single responsibility POV each tool has a singular functionality. It wouldn't make sense for the select tool to switch automatically to the move tool without the user input.

However from an actual animation workflow, it is much desired to have this! Which is why most of the time there is a single tool implemented to perform both Selection & basic transformation operations on raster & vector artwork, particularly in software like Adobe Animate or Toonboom Harmony which Pencil2D shares commonalities with.

For this particular request I don't see any issue. Having such a helper function for those who want this would be probably a huge performance boost 🥳
