[C#] support Json Serialization (#5752)

* support json serialization

* fix invalid json format.
* string must be written with double quotes.
* remove commma after the last object member.

* fix indent

* Revert "fix invalid json format."

This reverts commit d6820ed50c.

* quated string value.

* add cs-gen-json-serializer flag.

* fix preprocessor indent

* ENABLE_JSON_SERIALIZATION -> ENABLE_JSON_SERIALIZATION_TEST

* share TestBuffer method

* remove ENABLE_JSON_SERIALIZATION

* remove duplicated test data

* [windows] add nuget restore and copy test data.

* [docker mono] share msbuild settings with windows. add nuget restore and copy test data.

* add some note for json api.
