Introduced RunEndEncodedType and RunEndEncodedArray classes to represent run-end encoded arrays, including validation and logical length calculation. Integrated REE support into ArrowArrayFactory and IPC serialization/deserialization (ArrowStreamWriter, ArrowReaderImplementation, ArrowTypeFlatbufferBuilder, MessageSerializer). Added unit tests for REE array creation, validation, serialization, and indexing. This enables efficient handling of consecutive runs of the same value in Arrow .NET.

This PR attempts to add support for Run-End Encoded arrays by following established codebase patterns.
Notably:
ArrowTypeIdadded.RunEndEncodedArrayadded.RunEndEncodedTypenested type.This PR is missing targeted performance benchmarks as I could not see an established structure to add them into. Please let me know if, where and how you would like me to create these. They could be useful to observe performance variance from various data sparsity patterns and decide what to optimise.
Please let me know if this PR is missing anything else.
