[I] [Python] Support construction of Run-End Encoded arrays in pa.array(..) [arrow]

AlenkaF opened a new issue, #40273:
URL: https://github.com/apache/arrow/issues/40273

   ### Describe the enhancement requested
   
   We want to enable the construction of a Run-End Encoded arrays with `pyarrow.array` constructor. Example:
   
   ```python 
   >>> arr = [1, 2, 2, 3, 3, 3]
   >>> ree_arr = pc.run_end_encode(arr)
   >>> ree_type = pa.run_end_encoded(pa.int32(), pa.int64())
   
   >>> pa.array(ree_arr)    # Works
   <pyarrow.lib.RunEndEncodedArray object at 0x12ef46620>
   
   -- run_ends:
     [
       1,
       3,
       6
     ]
   -- values:
     [
       1,
       2,
       3
     ]
   >>> pa.array(arr, type=ree_type)   # Fails
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     File "pyarrow/array.pxi", line 343, in pyarrow.lib.array
       result = _sequence_to_array(obj, mask, size, type, pool, c_from_pandas)
     File "pyarrow/array.pxi", line 42, in pyarrow.lib._sequence_to_array
       chunked = GetResultValue(
     File "pyarrow/error.pxi", line 154, in pyarrow.lib.pyarrow_internal_check_status
       return check_status(status)
     File "pyarrow/error.pxi", line 91, in pyarrow.lib.check_status
       raise convert_status(status)
   pyarrow.lib.ArrowNotImplementedError: run_end_encoded
   ```
