1143a04f - [DebugInfo][DWARF] Emit DW_AT_abstract_origin for concrete/inlined DW_TAG_lexical_blocks (#136205)

[DebugInfo][DWARF] Emit DW_AT_abstract_origin for concrete/inlined DW_TAG_lexical_blocks (#136205) During the discussion under https://github.com/llvm/llvm-project/pull/119001, it was noticed that concrete DW_TAG_lexical_blocks should refer to corresponding abstract DW_TAG_lexical_blocks by having DW_AT_abstract_origin, to avoid ambiguity. This behavior is implemented in GCC (https://godbolt.org/z/Khrzdq1Wx), but not in LLVM. Fixes https://github.com/llvm/llvm-project/issues/49297.
