Fixed typo Python API
...
`mathutils.geometry.barycentric_transform` used `tri_a[1-3]` for the
target triangle, but in fact they are `tri_b[1-3]`

PyAPI: replace PyC_FromArray with typed functions
...
This was meant to be generic but introduced possible type errors
and unnecessary complication.
Replace with typed PyC_Tuple_PackArray_* functions.
Also add PyC_Tuple_Pack_* macro which replaces some uses of
Py_BuildValue, with the advantage of not having to parse a string.

PyAPI: add PyList_APPEND

This appends while giving ownership to the list, avoiding temp assignment.
This matches PyList_SET_ITEM which bypasses refcount's

real fix for [ #35097 ], (curve cap flipping).

previous commit was incorrect, the face flipping depended on the orientation of the curve.
fix by passing the bevel direction to the fill function so we can have a reliable front/back.
This also gives some speedup for all curve filling since we can avoid calculating the normal since its already known.
