lto/106540 - fix LTO tree input wrt dwarf2out_register_external_die
I've revisited the earlier two workarounds for dwarf2out_register_external_die
getting duplicate entries. It turns out that r11-525-g03d90a20a1afcb
added dref_queue pruning to lto_input_tree but decl reading uses that
to stream in DECL_INITIAL even when in the middle of SCC streaming.
When that SCC then gets thrown away we can end up with debug nodes
registered which isn't supposed to happen. The following adjusts
the DECL_INITIAL streaming to go the in-SCC way, using lto_input_tree_1,
since no SCCs are expected at this point, just refs.

PR lto/106334
* dwarf2out.cc (dwarf2out_register_external_die): Restore
original assert.
* lto-streamer-in.cc (lto_read_tree_1): Use lto_input_tree_1
to input DECL_INITIAL, avoiding to commit drefs.
