Fix manual licensing (#128630)

It has come to my attention that some of our licenses are incorrect, so I attempted to rectify a few of them based on given recommendations for:
clog - BSD-3
eigen - MPL-2.0
ffnvcodec - LGPL-2.1
-> **hungarian - Permissive (free to use)**
irrlicht - The Irrlicht Engine License (zlib/libpng)
-> **pdcurses - Public Domain for core**
-> **sigslot - Public Domain**
test - BSD-3
Vulkan - Apache-2.0 or MIT

This PR addressed the manual mismatches of licensing mentioned above (the two bolded, one is getting addressed in #128085, but as everything else is generated by pulling through other files, I did not address those. It is unclear what needs to be updated for the remaining to be accurate/if they're inaccurate today.
