The node socket declarations use the `N_()` macro to extract the name
and description of the socket.
This is quite redundant because since the syntax is always the same,
the extraction can be done automatically from the Python translation
module using regexes.
Four new regexes are introduced in bl_i18n_utils.settings:
- one extracts contextless messages from `add_input()` and
`add_output()`, the basic socket declarations with the names;
- one does the same, but for those sockets which declare a context
through `.translation_context()`;
- one extracts descriptions and error messages;
- one extracts geometry nodes field inputs.
In addition to making the code simpler and more legible, this change
extracts a few dozen messages which were not tagged with the proper
macro.
