feat(go): add go desrialization support via io streams

[ayush00git]

Why?

To enable stream-based deserialization in Fory's Go library, allowing for direct reading from io.Reader without pre-buffering the entire payload. This improves efficiency for network and file-based transport.

What does this PR do?

1. go/fory/buffer.go

Enhanced ByteBuffer to support io.Reader with an internal sliding window and automatic filling.

• Added reader io.Reader and minCap int fields.
• Implemented fill(n int) bool for on-demand data fetching and compaction.
• Updated all Read* methods (fixed-size, varint, tagged) to fetch data from the reader if not cached.

func (b *ByteBuffer) fill(n int) bool {
    if b.reader == nil { return false }
    // Compaction and stream reading logic
    ...
}

2. go/fory/fory.go

Added the DeserializeFromReader method as the primary public API for stream deserialization.

• Integrated io package.
• Implemented DeserializeFromReader to reset the buffer state and initiate deserialization from a stream.

func (f *Fory) DeserializeFromReader(r io.Reader, v any) error {
    defer f.resetReadState()
    f.readCtx.buffer.ResetWithReader(r, 0)
    // Deserialization logic
    ...
}

3. go/fory/reader.go

Ensured ReadContext correctly manages the buffer state when switching between memory-only and stream-backed modes.

• Updated SetData to reset the reader field.
