  [lldb] Report the unwound PC for WebAssembly caller frames (#212326)

RegisterContextWasm delegated the PC register read to
GDBRemoteRegisterContext, which reports the live innermost PC for every
frame. Resolving a variable whose DWARF location is a location list in a
caller frame therefore chose the entry using the innermost frame's PC
instead of the caller's, so the variable read back as unavailable even
though its location covered the caller's PC.

Return the program counter the WebAssembly unwinder recorded for the
frame (from qWasmCallStack) when reading a caller frame's PC, so the
location list entry uses the correct frame.
