[Python][Protocol] Chunk by chunk predictive map serialization protocol

[chaokunyang]

Feature Request

Chunk by chunk predictive map serialization protocol can be 2x faster than current one in pyfury. we should implement this new protocol.

See #925 for more details

Describe the solution you'd like

https://fury.apache.org/docs/specification/fury_xlang_serialization_spec/#map has a formulized spec:

All Map serializers must extend AbstractMapSerializer.

Format:

| length(unsigned varint) | key value chunk data | ... | key value chunk data |

map key-value chunk data

Map iteration is too expensive, Fury won't compute the header like for list since it introduce
considerable overhead.
Users can use MapFieldInfo annotation to provide the header in advance. Otherwise Fury will use first key-value pair
to predict header optimistically, and update the chunk header if the prediction failed at some pair.

Fury will serialize the map chunk by chunk, every chunk has 255 pairs at most.

|    1 byte      |     1 byte     | variable bytes  |
+----------------+----------------+-----------------+
| chunk size: N  |    KV header   |   N*2 objects   |

KV header:

• If track key ref, use the first bit 0b1 of the header to flag it.
• If the key has null, use the second bit 0b10 of the header to flag it. If ref tracking is enabled for this
  key type, this flag is invalid.
• If the key types of map are different, use the 3rd bit 0b100 of the header to flag it.
• If the actual key type of the map is not the declared key type, use the 4rd bit 0b1000 of the header to flag it.
• If track value ref, use the 5th bit 0b10000 of the header to flag it.
• If the value has null, use the 6th bit 0b100000 of the header to flag it. If ref tracking is enabled for this
  value type, this flag is invalid.
• If the value types of the map are different, use the 7rd bit 0b1000000 header to flag it.
• If the value type of map is not the declared value type, use the 8rd bit 0b10000000 of the header to flag it.

If streaming write is enabled, which means Fury can't update written chunk size. In such cases, map key-value data
format will be:

|    1 byte      | variable bytes  |
+----------------+-----------------+
|    KV header   |   N*2 objects   |

KV header will be a header marked by MapFieldInfo in java. For languages such as golang, this can be computed in
advance for non-interface types most times. The implementation can generate different deserialization code based read
header, and look up the generated code from a linear map/list.

Why serialize chunk by chunk?

When fury will use first key-value pair to predict header optimistically, it can't know how many pairs have same
meta(tracking kef ref, key has null and so on). If we don't write chunk by chunk with max chunk size, we must write at
least X bytes to take up a place for later to update the number which has same elements, X is the num_bytes for
encoding varint encoding of map size.

And most map size are smaller than 255, if all pairs have same data, the chunk will be 1. This is common in golang/rust,
which object are not reference by default.

Also, if only one or two keys have different meta, we can make it into a different chunk, so that most pairs can share
meta.

The implementation can accumulate read count with map size to decide whether to read more chunks.
