> Message serialization code optimizations: get rid of excessive buffer size

> Key: IGNITE-28122

> Project: Ignite
> Issue Type: Task

>
> Code-generated serialization mechanism uses the same buffer size checks on
> every field write just like the previous serialization mechanism.
> Right now fields of a message are written to the output stream in the same
> order they are declared in the message class. That's why message serializer
> has to perform buffer size checks for each individual field as it doesn't
> have any information about the size of the next field.
> But if one reorders the fields so that all fields of the same primitive type
> are written in one batch, it is possible to perform buffer size check only
> once. If number of fields and their type is known, serializer could ensure
> the space in the buffer in one check. This would allow to save some CPU
> cycles.
