_upb_MiniTable_Build() is now the general version of the function;
upb_MiniTable_Build() calls it and sets the platform to default/native.

upb_MiniTable_BuildEnum() -> upb_MiniTableEnum_Build()
upb_MiniTable_BuildExtension() -> upb_MiniTableExtension_Build()
also make the status pointer argument optional for the mini table builders

Remove circular dependencies that were bouncing back and forth between
msg_internal.h and mini_table/, including:
- splitting out each mini table subtype into its own header
- moving the non-reflection message code into message/
- moving the accessors from mini_table/ to message/

An enum MiniDescriptor simply encodes a set of valid `int32_t` values, so that the protobuf parser can test whether a given enum value is known or not.
The format implemented here is novel and needs to be documented. In short, the format is:
1. base92 values 0-31: 5-bit mask indicating presence or absence of the next five enum values.
2. base92 values 60-91: varint indicating skip over a region of enum values.
Negative enum values are encoded as their `uint32_t` equivalent.
