[ISSUE #10334] Make native CqCompactionFilter shim self-contained without rocksdbjni dependency

[lizhimins]

Summary

• Make the native CqCompactionFilter shim fully self-contained by including stub vtable implementations for all platforms, eliminating the DT_NEEDED dependency on librocksdbjni
• Remove ensureRocksDBNativeLoaded() from CqCompactionFilterJni — the shim no longer needs rocksdbjni loaded first
• Add synchronized lifecycle management (FILTER_LOCK) with proper destroyNativeFilter() called in preShutdown()
• Recompile all platform binaries (x86_64, aarch64, macOS arm64, Windows x64) with JDK 8 headers

Motivation

The previous shim had a DT_NEEDED on librocksdbjni-linux64.so. Since rocksdbjni has no SONAME, dlopen uses pathname-based dedup — different temp extraction paths produce different inodes, causing a second copy of rocksdbjni to be loaded into the process. Two copies of RocksDB global state (Env, thread pools) coexist, leading to intermittent SIGSEGV.

Changes

File	Change
CqCompactionFilterJni.java	Remove ensureRocksDBNativeLoaded(); add FILTER_LOCK + destroyNativeFilter(); simplify loadNativeShim()
ConsumeQueueRocksDBStorage.java	Call CqCompactionFilterJni.destroyNativeFilter() in preShutdown()
cq_compaction_filter.cpp	Remove #ifdef _WIN32 guard on stubs — now unconditional for all platforms
libcq_compaction_filter.so	Rebuilt x86_64 (self-contained, no DT_NEEDED on rocksdbjni)
libcq_compaction_filter_aarch64.so	Rebuilt aarch64 (self-contained)
libcq_compaction_filter.dylib	Rebuilt macOS arm64 (self-contained)
cq_compaction_filter.dll	Rebuilt Windows x64 with MSVC (self-contained)
docs/en/Native_RocksDB.md	Updated build instructions

Verification

# Verify no rocksdbjni dependency
objdump -p libcq_compaction_filter.so | grep NEEDED
# Shows only: libstdc++, libm, libgcc_s, libc

# CqCompactionFilterJniTest passed 5x on each platform:
# - Linux x86_64 (JDK 8): 5/5 PASS
# - Linux aarch64 (JDK 8): 5/5 PASS
# - Windows x64 (JDK 8): 5/5 PASS

Test plan

• CqCompactionFilterJniTest passes on Linux x86_64, aarch64, Windows x64, macOS arm64
• Full store module test suite passes (no regressions from this change)
• Repeated execution (5x per platform) shows no flakiness
• objdump -p confirms no DT_NEEDED on librocksdbjni
