lldbgdbremote.md: Update qWasmLocal result description (#170393)

The current description mistakenly specified that an address of a local
value in some address space is returned. When testing this with Wasm
runtimes that already implement this command, it can be observed that
the value itself is returned. The value itself may be an address for
languages that use shadow stack in Wasm linear memory, but the value of
an arbitrary local does not always contain that address.
