lld/elf: Deduplicate undefined symbol diagnostics
Before:
```
ld.lld: error: undefined symbol: f()
>>> referenced by test.cc:3
>>> /var/folders/c5/8d7sdn1x2mg92mj0rndghhdr0000gn/T/test-9c0808.o:(g())

```
Now:
```
ld.lld: error: undefined symbol: f()
>>> referenced by test.cc:3
>>> /var/folders/c5/8d7sdn1x2mg92mj0rndghhdr0000gn/T/test-0e07ba.o:(g())

>>> referenced by test2.cc:2
>>> /var/folders/c5/8d7sdn1x2mg92mj0rndghhdr0000gn/T/test2-6bdb24.o:(asdf())
ld.lld: error: undefined symbol: k()
>>> referenced by test.cc:5
>>> /var/folders/c5/8d7sdn1x2mg92mj0rndghhdr0000gn/T/test-0e07ba.o:(j())
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
If there are more than 10 references to an undefined symbol, only the
first 10 are printed.
Fixes PR42260.
