[PR] fix(java): fix race condition in blocking queue serializers [fory]

["zhan7236 (via GitHub)" <gi...@apache.org>]

URL: https://github.com/apache/fory/pull/2956

   ## What does this PR do?
   This PR fixes the race condition concern raised in PR #2955 review by maintainer @chaokunyang.
   
   ## Problem
   The original implementation calculated capacity using:
   ```java
   int capacity = abq.remainingCapacity() + abq.size();
   ```
   This could cause race conditions when the queue is being modified concurrently between the two calls.
   
   ## Solution
   Use reflection to directly read the capacity field:
   - For `ArrayBlockingQueue`: Read `items` array length (capacity is array length)
   - For `LinkedBlockingQueue`: Read `capacity` field directly
   
   This follows the same pattern used by `ArraysAsListSerializer` which uses `Platform.objectFieldOffset()` for safe field access.
   
   ## Related issues
   Follow-up to #2955 addressing: https://github.com/apache/fory/pull/2955#pullrequestreview-2508169408
   
   ## Does this PR introduce any user-facing change?
   No - this is an internal implementation fix.
   
   ## Benchmark
   N/A - no performance impact expected, both approaches are O(1).
