…/-O3 ### What problem does this PR solve? Issue Number: close apache#63927 Problem Summary: Building BE unit tests with TSAN (-O1) or RELEASE (-O3) causes undefined reference linker errors for SegmentWriter::_is_mow(), SegmentWriter::_is_mow_with_cluster_key(), and their VerticalSegmentWriter counterparts. Root cause: commit 74aa0ca defined these methods with the `inline` keyword in .cpp files. At -O0 (ASAN), the compiler ignores `inline` and exports the symbol, so linking succeeds. At -O1/-O3, the compiler inlines the function and does NOT export the symbol. When commit 4616202 introduced TestSegmentWriter (a friend subclass) that calls these private methods from a different translation unit, the linker cannot find the symbols. Fix: move the inline definitions from .cpp files into the header files as class-internal inline definitions, so they are visible to all translation units. ### Release note None ### Check List (For Author) - Test: Unit Test - Added segment_writer_mow_check_test.cpp with 7 test cases covering all logic branches for both SegmentWriter and VerticalSegmentWriter - Behavior changed: No - Does this need documentation: No
