Once the GitHub action is fixed, these will be auto-updated whenever
necessary. I realized it would be a good idea to add them back first,
though, just to make sure nothing breaks before we enable the
auto-updating.
We need to sharpen the distinction between messages and extensions in the mini
descriptor encoder, so split the code paths for each.

- upb_DefPool_FindExtensionByMiniTable() has been promoted to a public function.
- There are now zero uses of the internal reflection headers outside of upb core (but still a few left in generated code).

We had _upb_Message_New(), which created a message from a mini table and was
being used outside of upb even though it is an internal-only function.
We also had upb_Message_New(), which created a message from a message def.
Now there is a single public function, upb_Message_New(), which creates a
message from a mini table and covers all use cases. (The internal version has the same definition and is used for inlining.)

Prior to this CL, users were relying on `field->descriptortype` to get the field type. This almost works, as `field->descriptortype` is almost, but not quite, the field type of the field. In two special cases we deviate from the true field type, for ease of parsing and serialization:
- For open enums, we use `kUpb_FieldType_Int32` instead of `kUpb_FieldType_Enum`, because from the perspective of the wire format, an open enum field is equivalent to int32.
- For proto2 strings, we use `kUpb_FieldType_Bytes` instead of `kUpb_FieldType_String`, because proto2 strings do not perform UTF-8 validation, which makes them equivalent to bytes.
In this CL we add a public API function:
```
// Returns the true field type for this field.
upb_FieldType upb_MiniTableField_Type(const upb_MiniTable_Field* f);
```
This will provide the actual field type for this field.
Note that this CL changes the MiniDescriptor format. Previously MiniDescriptors did not contain enough information to distinguish between Enum/Int32. To remedy this we added a new encoded field type, `kUpb_EncodedType_ClosedEnum`.

On a 32-bit build, sizeof(upb_Array) was not aligned to 8, and so we were allocating a block of memory that was too small.
Our 32-bit GitHub tests did not catch this, probably because the 32-bit build is not running ASAN. The bug manifested in the 32-bit PHP build.
