Slow dataset serialization using TMVCJsonDataObjectsSerializer.DataSetToJsonArray

[dsonda]

TMVCJsonDataObjectsSerializer.DataSetToJsonArray is very slow do serialize a dataset containned in a class (DataModule or Form) with high number os class members.

The TMVCAbstractSerializer.GetNameAs and TMVCAbstractSerializer.IsIgnoredComponent are very slow with big classes (high number of fields) to read attributes using RTTI.

Sample attached.

Hello,
I Change MVCFramework.Serializer.JsonDataObjects to read one time attributes,
Test for me, please.

MVCFramework.Serializer.JsonDataObjects.zip

[dsonda]

Before, it took about 25 seconds to serialize in my sample.
After changes, it took 0,215 seconds.
Great job!
Could you merge this change in master?

Good job. Let me do some tests using the 108 unit tests, and then the patch will go in the repo
