Over the year, changes in how image packedfiles were handled broke the
fallback case of missing packed data in a few places, this commit fixes
proper cleanup of invalid packed files in the Image's list of
packedfiles.
In addition, also do not create inplicit sharing info when the read data
is `nullptr`.
All of these changes should be trivial, like using `string` read/write
code for strings, and a convert a few usages of 'raw data' read/write
calls to the 'struct' ones.
No behavioral changes expected here.
I found that `packedmap` is effectively unused when I worked on #123243.
The only function that wrote to it was `blo_make_packed_pointer_map`
and that is never called. Packed data already used the normal `datamap` as fallback.

These remain linked, so data remains to be read/loaded from the packed
version from the library (making this a useless and wasteful
duplication, also changes could be perceived as lost). Tooltip was also
reading "Unpack all files packed **into this .blend** to external ones",
so that bring it in line with the tooltip.
This came up in #122033

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.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
Accessing the file size returns -1 on error, for file packing this
was passed directly to an allocation which would wrap around to
SIZE_T_MAX and fail to allocate. In other cases zero was treated
as an error value but -1 wasn't.
Add checks for the error return value, also warn that packing files over
2gb isn't supported.
Also see #103343.
Couldn't move two files yet:
* `softbody.c`: The corresponding regression test fails. It seems like the
conversion to C++ changes floating point accuracy, but it's not clear where that happens exactly.
* `writeffmpeg.c`: Is a bit more complex to convert because of the static array in `av_err2str`.
