lldb-{12…19,devel}: Python is a lib dependency

[markmentovai]

Python was only specified as a build dependency, but for lldb, it’s actually a lib dependency. For example, after removing python310:

--->  Scanning binaries for linking errors
--->  Found 3 broken files, matching files to ports
--->  Found 3 broken ports, determining rebuild order
You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt:
 lldb-12 @12.0.1
 lldb-13 @13.0.1
 lldb-14 @14.0.6

% lldb-mp-12
dyld[…]: Library not loaded: /opt/local/Library/Frameworks/Python.framework/Versions/3.10/Python
  Referenced from: <…> /opt/local/libexec/llvm-12/lib/liblldb.12.0.1.dylib
  Reason: tried: '/opt/local/Library/Frameworks/Python.framework/Versions/3.10/Python' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/opt/local/Library/Frameworks/Python.framework/Versions/3.10/Python' (no such file), '/opt/local/Library/Frameworks/Python.framework/Versions/3.10/Python' (no such file)
zsh: abort	lldb-mp-12

This may be necessary for versions before lldb-12 as well, but I’ve only tested lldb-12 and later.
