The asset handle type is supposed to be replaced by the asset representation type. It is designed for the asset system as opposed to the file browser backend. Withd421ebac5e,d04cd3f3e6andf6a6b27ac1, it can now do everything that is needed in Python to be a replacement. With this commit the asset handle type and the file handle type it uses is almost entirely replaced in Python files (only for the asset view template we require a collection property taking asset handles still, for internal reasons.) Part of #102877 and #108806.
