Don't import `ImplWitnessTable` into the `constants` block, because we generally don't put `Unique` constants there. This matches the handling of the other kinds of `Unique` constants. In order to keep the instruction visible in formatted SemIR, add it to the `imports` block instead. Also fix a bug in the instruction formatter that resulted in instructions in the `imports` block being omitted from the output if they were only referenced by earlier instructions in the `imports` block and by instructions in the `constants` block. This was already resulting in some referenced instructions being omitted from the output, but also occurred frequently for `impl_witness_table` instructions after this change because it is common for the only reference to those instructions to be from `impl_witness` instructions in the `constants` block.
