[C++] Implement meta string encoding algorithm for C++

[chaokunyang]

Is your feature request related to a problem? Please describe.

We've implemented meta string encoding algorithm in https://fury.apache.org/docs/specification/fury_xlang_serialization_spec#meta-string for java in #1514 , it's time to implement it in c++.

Describe the solution you'd like

Java implementation in #1514 can be taken as a reference. But note that the meta string encoding algorithm is used for encode field name only, so the special charater can't be . or $, thus the implementation will be simpler

Additional context

#1413
