Make "open with" open in a new task

[RichardLuo0]

Currently if I use another app to open file from materialFile, the task looks like this.
It is not only very confusing, sometimes this can lead to crash. For example, when I open zarchiver text editor from materialfile, if I open the recent screen or switch apps, sometimes I back to the zarchiver (in material file task), the zarchiver will crash (ANR).
