c301c2ca28 Breaking Change: Remove deprecated UseDeprecatedLegacyJsonFieldConflicts()

4f076d951f Add metadata annotations for generated Python protobuf symbols. 
The pyi generator now includes Kythe annotations for:
*   Extension field constants (e.g., `EXTENSION_FIELD`).
*   Field number constants (e.g., `STRING_FIELD_FIELD_NUMBER`).
*   `Create` methods in generated Stubby client classes.

These annotations allow the Python indexer to link these generated symbols back to their definitions in the `.proto` files.

a70115f33f Breaking change: Add [[nodiscard]] to many APIs. 
This covers two types of failures:
* Methods that are logically const and failure to consume the result indicates a bug
  (an unnecessary call, etc.)
* Methods that return significant errors (failure to parse, etc.) that should not be
  unintentionally ignored.

232f409e96 Avoid PyObject_CallMethod with pending errors, which always asserts. 
This can happen from ignored errors during build (e.g. missing option dependencies).

4459a20205 Support more chars in type URLs in the Python text-format parser. 
Change the Python text-format parser to allow for more characters and formats
in the type URL prefixes of expanded Any protos. This follows a recent
change to the text-format spec which we are now closely following.

1eb4e5290a Python Proto scalar repeated numpy binding. 
Add __array__ magic method to scalar repeated field. The default returned dtype of numpy/tensorflow usages like np.arrary() np.asarray() will be change.
Cpp_Type | np.array() dtype | Old tf.reshape() dtype | New dtype
float.   | float64/float64  | float32/float32.       | float32
double.  | float64/float64. | float32/float32.       | float64
int32.   | int64/float64.   | int32/float32.         | int32
int64.   | int64/float64.   | int32/float32.         | int64
uint32.  | int64/float64.   | int32/float32.         | uint32
uint64.  | int64/float64.   | int32/float32.         | uint64
bool.    | bool/float64.    | bool/float32.          | bool
enum     | int64/float64    | int32/float32          | int32
string   | U/float64        | string/float32         | U (Unicode string)
bytes    | S/float64        | string/float32.        | S (Byte string)

Performance improvement:
For non-string repeated:
  -upb/cpp are about 50-100 times faster.
  -pure python is ~3x times faster.
For string repeated: numbers are noise, no regression (maybe a slight win)

be2d06dd93 Pass arenas down to map methods, and avoid accessing arena_ directly in map field implementation. 
Note that we can't change any public-facing API's that need an arena pointer, as this would be a breaking change. Additionally, assignment operators need the arena pointer, but can't take additional arguments.

This is in preparation for removing the arena_ member from maps.
