UI: use "Save As" when saving un-saved image/text files

Now the behaviors are consistent for blend, image and text files:

- If the file is not writable, will report it.
- If the file is new (without a path), save as will be used.
- If the file was deleted, will try to recreate it.

RNA properties subtypes enum: sync definitions everywhere

Some subtypes never made it to all neccessary places when they were
introduced. This was throwing warnings when accessing such a properties
subtype from python.

The sub_type enums were also defined in 4 different places:
- RNA_types.h 'PropertySubType'
- rna_rna.c 'rna_enum_property_subtype_items'
- rna_rna.c 'subtype_items'
- bpy_props.c as multiple enums

This patch syncs the definitions across all places so that they are the
same everywhere. It also looks redundant to define these twice in
rna_rna.c, now just use 'rna_enum_property_subtype_items' there (and get
rid off 'subtype_items').

Also moved 'POWER' & 'TEMPERATURE' to number enum in bpy_props (these
were defined in the array enum).

Fixes T82167.

CustomData color copying: use interpolated alpha

The alpha of the first layer was always used
here since introduction in rBee4453f08369 and was not updated when
customdata support for alpha was added.

Now also use the interpolated alpha.

thx @brecht noticing!

Fix blend_color_interpolate_byte returning wrong alpha in certain case

When the combined alpha [the 'tmp' variable having the mixfactor applied
already] - reached zero it was handled like a no-op (for the alpha as
well) and just copied the first color.

So e.g mixing 255/255/255/255 with 0/0/0/0 with a factor of 1.0 gave
alpha of 255, which looks wrong.

cases where tmp gets zero:
src1 alpha:0 src2 alpha:whatever mixfactor 0.0
src1 alpha:whatever src2 alpha:0 mixfactor 1.0
src1 alpha:0 src2 alpha:0 mixfactor whatever

Now set alpha to zero in that case.

PyAPI: point sys.executable to the Python binary

`sys.executable` is documented to be a Python interpreter or None.

This was set to Blender's executable which caused the multiprocessing
module to spawn new instances of Blender instead of Python on WIN32.
See issue described in D7815.

Deprecate 'bpy.app.binary_path_python' & warn when using.

Blender's executable remains accessible via `bpy.app.binary_path`.

Modified 04c5471ceefb4, setting `sys.executable` instead of using
Py_SetProgramName, which is needed for a bundled Python installation.
