Add __strlcpy_chk symbol for Minecraft 1.21.130.3+ compatibility

[AndrewX98]

Minecraft 1.21.130.3 uses libPlayFabMultiplayer.so which requires the __strlcpy_chk symbol from Bionic libc. Without it, the game fails to load:

dlopenfailed: cannot locate symbol "__strlcpy_chk"

This PR adds the missing implementation following the same pattern as other fortified functions (__memcpy_chk, __strcpy_chk , etc.).

Changes:

common.h : Added function declaration
common.cpp : Added implementation with bounds checking, registered in
add_string_shimmed_symbols

Tested with: Minecraft 1.21.130.3, 1.21.144

((((Very important remove the libmcpelauncher-updates.so))))

You should close this pull request and create a new one without all the refactoring and reformatting.

I'm only a lurker here, but the number of lines changed in this pull request makes it hard to review.
