Complete element setter/getter functional API for all GraphBLAS types

Previously matrix.py, vector.py, and scalar.py only exposed `set_bool`
and `bool` functions for accessing elements, even though SuiteSparse:GraphBLAS
supports many more types. This fills out the functional API to cover every
type the C library supports, following the existing `set_bool` / `bool`
pattern exactly.

Adds setter/getter pairs for: int8, int16, int32, int64, uint8, uint16,
uint32, uint64, fp32, fp64, fc32, fc64.

The complex types (fc32, fc64) are gated on `supports_complex()` so the
functions are only defined on builds compiled with SuiteSparse complex
support enabled (fc32/fc64 are GxB extensions, and the standard
suitesparse.sh build disables them via GxB_NO_FC32 / GxB_NO_FC64).

Each new function carries a doctest that round-trips a value through
its setter and getter. Doctest counts after this change:

  matrix:  97 attempted, 0 failed
  vector:  90 attempted, 0 failed
  scalar:  81 attempted, 0 failed
  total:   268 attempted, 0 failed
