2025.12.16.1424 - Raw dT node, fixes for ARM headless & precise bounds

Here's a bunch of fixes for the ARM and precise bounds calculations. Also new Raw dT node!

New Features:

• Added Raw dT and Raw 1/dT ProtoFlux nodes that expose raw delta time (based on report by @.fulgens, issue #5998) -- This is delta time without any clamping or filtering -- In case of hitches, this will output potentially very large values that can destabilize some simulations - use with caution!

Tweaks:

• Disabled sources of bounds are now excluded from calculating precise bounds (based on report by @yoshiyoshiyoshiyoshiyoshyoshyosh, issue #5995)

Locale:

• Merged Korean locale update by @mirpasec
• Merged Chinese locale update by modimobeikete
• Merged German locale update by @muppeq

Fixes:

• Fixed SRAnipal or HP Omnicept getting initialized when running through SteamLink
• Patch various ARM64 libraries to avoid loading error (reported by hantabaru1014, issue #5971, fixed by @j4.lc) -- Move the ARM64 Brotli native library to the correct folder, which patches the not found error -- Build Assimp on ARM64 against lower requirements target to avoid missing libraries when used on older machines -- This also fixes freetype not loading on systems not shipping it (reported by Orion Moonclaw, issue #5982)
• Disable AVX512 on Linux for compressonator to avoid common crash (reported by @kyuvulpes, mxjessie, issue #5970 and @reddneko, @hayden_fluff, @bredo, issue #5972)
• Fixed PointOnUVSphere being calculated incorrectly (reported by @yoshiyoshiyoshiyoshiyoshyoshyosh, brecert, issue #5991)
• Fixed precise bounds being calculated incorrectly in various cases for primitive colliders (based on report by @yoshiyoshiyoshiyoshiyoshyoshyosh, issue #5994)
• Re-build FreeImage without neon for ARM devices to prevent a crash (reported by Kulza in #5996)
