Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
We shouldn't expose the VirtIO GPU3DDevice constructor as public method,
so instead, let's use the usual pattern of a static construction method
that uses the constructor within the method.
This code attempts to copy the `Protocol::Resource3DSpecification`
struct into request, starting at `Protocol::ResourceCreate3D::target`
member of the `Protocol::ResourceCreate3D` struct.
The problem is that the `Protocol::Resource3DSpecification` struct
does not having the trailing `u32 padding` that the `ResourceCreate3D`
struct has. Leading to memcopy overrunning the struct and corrupting
32 bits of data trailing the struct.

- Memory copy function overflows the destination buffer.
This commit flips VirtIOGPU back to using a Mutex for its operation
lock (instead of a spinlock). This is necessary for avoiding a few
system hangs when queuing actions on the driver from multiple
processes, which becomes much more of an issue when using VirGL from
multiple userspace process.
This does result in a few code paths where we inevitably have to grab
a mutex from inside a spinlock, the only way to fix both issues is to
move to issuing asynchronous virtio gpu commands.
