Richard Smith e8cd229e74 When performing an impl lookup, only import impls for related interfaces. (#6040) 
This avoids impl lookups involving, say, `Core.Int` pulling in all ~65
impls in "prelude/types/int", which resulted in a lot of unnecessary
importing work, followed by a lot of unnecessary inst namer and inst
formatter work.

Before:
```
Ran 1335 tests in 6186 ms wall time, 146818 ms across threads
  Slowest tests:
  - toolchain/check/testdata/interop/cpp/function/arithmetic_types_bridged.carbon: 5611 ms, 5532 ms in Run
  - toolchain/check/testdata/interop/cpp/function/operators.carbon: 2034 ms, 1981 ms in Run
  - toolchain/check/testdata/primitives/import_symbolic.carbon: 1796 ms, 1786 ms in Run
  - toolchain/lower/testdata/operators/arithmetic.carbon: 1729 ms, 1728 ms in Run
  - toolchain/lower/testdata/function/generic/call_recursive_sccs_deep.carbon: 1700 ms, 1697 ms in Run
[==========] 1335 tests from 1 test suite ran. (682 ms total)
```

After:
```
Ran 1335 tests in 2419 ms wall time, 109587 ms across threads
  Slowest tests:
  - toolchain/check/testdata/interop/cpp/function/arithmetic_types_bridged.carbon: 1748 ms, 1665 ms in Run
  - toolchain/check/testdata/interop/cpp/function/operators.carbon: 1106 ms, 1057 ms in Run
  - toolchain/lower/testdata/function/generic/call_recursive_diamond.carbon: 1044 ms, 1041 ms in Run
  - toolchain/lower/testdata/function/generic/call_recursive_sccs_deep.carbon: 1015 ms, 1012 ms in Run
  - toolchain/lower/testdata/operators/arithmetic.carbon: 998 ms, 997 ms in Run
[==========] 1335 tests from 1 test suite ran. (652 ms total)
```

That's still slower than it should be, but a large improvement
nonetheless.

Fixes #6029
