support cast as json

[SeaRise]

What problem does this PR solve?

Issue Number: close #8307 close #8371

Problem Summary:

What is changed and how it works?

Because json and string are both DataTypeString in tiflash, cast as json cannot be implemented in FunctionsTiDBConversion.h, So here we implement cast as json separately.
support

• CastIntAsJson
• CastRealAsJson
• CastDecimalAsJson
• CastStringAsJson
• CastTimeAsJson
• CastDurationAsJson
• CastJsonAsJson

Introduce simdjson v3.6.0 https://github.com/simdjson/simdjson/releases/tag/v3.6.0 for cast string as json.
Because some functions require tipb::FieldType, pass tipb::FieldType in DAGExpressionAnalyzerHelper.
