avutil/vulkan_loader: Avoid redundant strings and relocations
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).
