SymbolResolverFindFde
Description
Look up the .eh_frame FDE that describes how to unwind through the function at runtime_addr. Populates *out_cfi, *out_fde, and the module’s runtime load base so the caller can run the CFI VM (via DwarfCfiBuildRow) and compute a CFA in the runtime address space.
Success
Returns true; all three output parameters set.
Failure
Returns false when runtime_addr falls outside any loaded module, the module has no .eh_frame, or no FDE covers the address.
