This commit moves generated `RNA_blender.h`, `RNA_prototype.h` and
`RNA_blender_cpp.h` headers to become C++ header files.
It also removes the now useless `RNA_EXTERN_C` defines, and just
directly use the `extern` keyword. We do not need anymore `extern "C"`
declarations here.

Add new ID_IS_EDITABLE macro that checks if the ID can be edited in the
user interface. Replace usage of ID_IS_LINKED where it is used with this
meaning.
Also add a corresponding ID.is_editable property for Python.
This prepares for the ability to edit some linked datablocks for brush
assets.

The depsgraph CoW mechanism is a bit of a misnomer. It creates an
evaluated copy for data-blocks regardless of whether the copy will
actually be written to. The point is to have physical separation between
original and evaluated data. This is in contrast to the commonly used
performance improvement of keeping a user count and copying data
implicitly when it needs to be changed. In Blender code we call this
"implicit sharing" instead. Importantly, the dependency graph has no
idea about the _actual_ CoW behavior in Blender.
Renaming this functionality in the despgraph removes some of the
confusion that comes up when talking about this, and will hopefully
make the depsgraph less confusing to understand initially too. Wording
like "the evaluated copy" (as opposed to the original data-block) has
also become common anyway.

Move the three current 'status variables' (stop, update and progress)
into a single 'WorkerStatus' struct. This is cleaner and will allow for
future workin this area without having to edit tens of 'startjob'
callbacks signatures all the time.
No functional change expected here.
Note: jobs' specific internal code has been modified as little as
possible, in many cases the job's own data still just store pointers to
these three values. Ideally in the future more refactor will be using a
single pointer to the shared `wmJobWorkerStatus` data instead.

This moves the remaining `.c` files in the following `editors` folders to C++:
`physics`, `screen`, `sound`, `space_buttons`, `space_file`, `space_graph` and `space_image`.
One exception is `fsmenu.c` which has platform specific issues on macos and
windows. E.g. the `Carbon/Carbon.h` include also declares a `Collection` type that collides
with ours.
Also see #103343.
