std.process.browse should use internal functions for executing subprocess

Description

The browse function predates std.process, and uses its own mechanisms to create a process. This resulted in at least one bug (issue 24824).

The internals should just call `spawnProcess` or whatever it takes to properly execute the browser process, instead of reimplementing most of it.

Note, this is a "reopening" of issue 6496. I think that was closed in error.
