more work on socket data types

Python: Expose WM is_interface_locked to python.

This patch exposes the Window Manager `is_interface_locked` as a read
only property to python.

This property is needed to allow script writers to detect if a job is
running with locked interface like the Alembic exporter.

Fix compile errors and broken drawing after changes in master

There are still some issues left after the changes in master:
* Some optimizations need to be redone differently
* Color-space handling needs to be redone differently
* Upside-down drawing is broken

Cleanup: Alembic, split source files into reader and writer

This separation between reader and writer code is part of Milesone 2 of
T73363.

In this commit the reader and writer classes are separated into their
own files, any `#include` and `using` statements are cleaned up, and
some separator comments have been removed.

No functional changes.

Alembic: fix unit test on Windows

There are two issues solved in this commit:

- Our Windows buildbot has slightly different floating point errors than
the Linux one, which meant a larger delta was required for float
comparisons.
- The test performs an export to a temporary Alembic file and
subsequently imports it. Deleting the temporary file was impossible on
Windows because it was still in use. This is now resolved by first
loading the default blend file before deleting the Alembic file.

UI: Use crosshair cursor for Extrude to Cursor tools

Since this tool doesn't perform selections when you click, it's important that the cursor helps communicate that something else will happen.
