hle: Handle GPU profiler and debugger device path correctly (#4138)
This fix a warning on "慟哭そして…" by handling correctly the debug mode
flag.

When debug mode isn't enabled, opening /dev/nvhost-dbg-gpu or /dev/nvhost-prof-gpu should fail with a not implemented error code.

This implement this behaviour and also define stubbed interfaces for
completness.

Update units of memory from decimal to binary prefixes (#3716)
`MB` and `GB` can either be interpreted as having base-10 units, or
base-2. `MiB` and `GiB` removes this discrepancy so that units of memory
are always interpreted using base-2 units.

Fix a potential GPFIFO submission race (#3378)
The syncpoint maximum value represents the maximum possible syncpt value at a given time, however due to PBs being submitted before max was incremented, for a brief moment of time this is not the case which could lead to invalid behaviour if a game waits on the fence at that specific time.

This removes the need to pass in whether the command is a Tipc command or a Hipc command to the exception constructor.
