To do so, concatenate all the names together to one big string
name1\0name2\0....lastname\0\0. This avoids the pointer in
the FunctionLoadInfo structure and thereby moves vk_load_info
into .rodata (and makes it smaller by 888B).

Saves 16B per entry here (four of these 16 bytes are padding);
leads to 1776 B of savings in each file that uses
ff_vk_load_functions().

There are three possible names for the functions requested;
they only differ in an extension: "", "EXT" or "KHR".
Yet vk_load_info contained pointers to all these strings.
This is wasteful and this commit changes it to avoid
the latter two strings. This saves 6353B of strings,
1776 B of .data.rel.ro as well as 5328 B due to the removed
relocations (corresponding to 2 * 111 removed pointers)
in lavc/vulkan_decode.o alone (ff_vk_load_functions()
is inlined in lavfi/vulkan_filter.c, lavu/hwcontext_vulkan.c
and lavc_vulkan_decode.c, so the savings are three times
this for shared builds; for static builds, the number may
be smaller depending upon whether strings are deduplicated).
