Breakages on Windows. Not going to bother supporting Vulkan v1.3 on
this.

This reverts commit d16b498f.

This type is a currently too obscure to bother fixing, and due to the
array of pointers specialty, too difficult currently.

The files created during debugging in the root directory.

The free function needs to be included on some compilers, and is brought
in via the cstdlib C header.

Vulkan structures are C-based, thus no easy cleanup mechanism exists, so
this adds a function that attempts to do this, under the assumption that
any of the struct's pointer members with names of 'p[A-Z]' are owned by the
struct and can be safely
deleted.

Another members that are pointers that don't start with 'p[A-Z]' are
assumed to be externally managed and not deleted, nor any 'pointer to
pointers' type members.

The value of an enum has been implicitly based on a signed value.
However no Vulkan enum value has been negative, until v175, with the
introduction of the first one. This thus changes to support signed
values.
