Python 3.14 support

[shusvr]

Version and Platform (required):

• Binary Ninja Version: 5.3.9387-dev Personal (0d8b5e76)
• Edition: Non-Commercial
• OS: Arch linux
• CPU Architecture: x64

Bug Description:
Binary ninja fails to load the native plugin pythonplugin if system has only python 3.14 installed. And I get these error & warning:

[PythonPlugin] Failed to find suitable libpython! Specified python library does not exist: 
[Core] Native plugin pythonplugin failed to load

I have

$ ls /usr/lib/ | rg 'libpython'
lrwxrwxrwx     - root root  13 Feb 18:31  libpython3.14.so -> libpython3.14.so.1.0
.rwxr-xr-x  5.9M root root  13 Feb 18:31  libpython3.14.so.1.0
.rwxr-xr-x   14k root root  13 Feb 18:31  libpython3.so

This causes all python plugins to fail to load.

If I add a symlink libpython3.13.so.1.0 then the previous warning & error are gone but I doubt this is a robust long term solution.

Expected Behavior:
I expected binary ninja to load properly without errors and warnings and to have plugins load correctly.

Set the python.interpreter setting to /usr/lib/libpython3.14.so.1.0. Right now we only automatically search for up to 3.13.

This is required to support Ubuntu 26.04 (which releases this month) so we intend on fixing the fact we do not search for this version of python in the upcoming stable.
