Due to unlucky power off or a crash crash when first starting the game
the prefix can end up in corrupted state with no obvious way of
troubleshooting.
This is an attempt at ensuring that the prefix was created successfully
and force-recreate it if it wasn't.

If a Steam user runs Steam from a terminal, puts it in the background
and then exits from that terminal, or if they restart their desktop
session from a terminal (as in ValveSoftware/Proton#6277) and then exit
from that terminal, then we can inherit a stdout and/or stderr file
descriptor pointing to an invalid file descriptor. Writing to such a
file descriptor fails with EIO. Similarly, we could get write errors
as a result of OS state, such as ENOSPC if we are writing to a disk
that is full, or EPIPE if a stream to a logging framework such as the
systemd journal has been shut down.
In sufficiently pathological situations, the file descriptor could even
become invalid while the `proton` script is running, so even checking
for validity on startup would not be enough to prevent this.
The ability to log to stderr is important but not functionally critical,
and it's not like there is anything we can usefully do about a write
failure here (or even anywhere we can usefully put a warning message),
so just ignore write errors. This is similar to the behaviour of the
`logging` framework in the Python standard library (which writes to
`stderr` if a user-defined handler fails, but takes no other action)
and also similar to the approach taken to solve
ValveSoftware/steam-for-linux#8069.

This comments out all of the games that do not need the MFDXGI hack on
the experimental branch because the experimental branch has support for
shared resources.
This separates out the games that only need shared resources in order to
play video correctly without the MFDXGI hack. El Hijo (853050) and Labyrinth
City: Pierre the Maze Detective (1421790) were also added.
If a stream ID is not set, gstreamer will generate random stream IDs for
the streams in downstream elements. This can cause decodebin to generate
its source pads in a non-deterministic order, as decodebin takes into
account the stream IDs when sorting the source pads.
This patch includes some changes from Arek Hiler.
CW-Bug-Id: #21192
1. ElementImpl trait requires GstObjectImpl
2. gst logging macros are no longer globals prefixed with gst_, they
live inside gst:: instead
3. element is not longer passed around in many places, it can be
accessed as self.obj() or self.instance()
4. query_default is now a part of gst::Pad and takes the pad as an argument
5. some constructors were changed to use from_$type()
6. query.view_mut() returns QueryViewMut
7. ElementFactory::make now returns a builder that we have to .build()
There are some extra cleanups as well:
1. spurious 'mut' and '&' are removed, a lot of that can be infered or
were turned into a dereference by the compiler anyway
2. !bla.is_ok() are now bla.is_err()
3. some unneeded imports were removed
