[OE-core][PATCH] lib: Fix dependencies on SPDX code

[Joshua Watt <jpewhacker@gmail.com>]

The SPDX library code was being ignored from taskhash calculations due
to accidentally being omitted from BBIMPORTS. This meant that changes in
the code or dependent variables would not cause the task to rebuild
correctly.

In order to add spdx_common, convert the `Dep` object from a named tuple
to a frozen dataclass. These function more or less equivalently, but the
bitbake code parser cannot handle named tuples.
