[python] PY-87496 The user experience of debugging has changed a lot

PyDebugProcess implements PyStepIntoSupport (pydevd path unchanged).
PythonDapDebugProcess implements PyStepIntoSupport:
justMyCode=true: "Step Into My Code" enabled, "Step Into" disabled;
justMyCode=false → "Step Into My Code" disabled with a tooltip.
Add PyDapStepIntoAction as a DAP-aware replacement for the platform "Step Into" action in the debug toolbar.
