Size of CodeQL binary distribution has almost trippled since 2021

**Description of the issue**

I've noticed that the size of the CodeQL binary distribution only knows one direction - upwards.

2021-04-29: 242 MB compressed, 476 MB uncompressed
2022-12-03: 417 MB compressed, 1.1GB uncompressed
2023-09-04: 541 MB compressed, 1.4 GB uncompressed

Now this is of course somewhat expected as there are new languages being added over the course of time and space is free; expect when it slowly isn't^^
I'm wondering whether there are some easy improvements possible.
For example `fdupes -r -S -m .` in the `tools/`directory results in
```shell
89 duplicate files (in 8 sets), occupying 119.7 megabytes
```
and for example all of these files are identical:

```
4092064 bytes each:
./linux64/lib64__trace
./linux64/lib/x86_64-linux-gnutrace.so
./linux64/lib/x86_64-linux-gnu_xeon_phi_trace.so
./linux64/lib/x86_64-linux-gnu_x86_64_trace.so
./linux64/lib/x86_64-linux-gnu_i686_trace.so
./linux64/lib/x86_64-linux-gnu_haswell_trace.so
./linux64/lib_xeon_phi_trace.so
./linux64/lib_x86_64_trace.so
./linux64/lib_haswell_trace.so
./linux64/lib64trace.so
./linux64/lib64_xeon_phi_trace.so
./linux64/lib64_x86_64_trace.so
./linux64/lib64_i686_trace.so
./linux64/lib64_haswell_trace.so
./linux64/x86_64-linux-gnutrace.so
./linux64/x86_64-linux-gnu_xeon_phi_trace.so
./linux64/x86_64-linux-gnu_x86_64_trace.so
./linux64/x86_64-linux-gnu_i686_trace.so
./linux64/x86_64-linux-gnu_haswell_trace.so
```

The `swift/` subdirectory occupies more than 500 MB; maybe it is possible to try to build some of these binaries with `-Osize` or something similar?
Feel free to close this issue, if you think this is not worthwhile or there are no easy gains.

Start by inspecting the tools/ directory and the swift/ subdirectory, then run the mentioned fdupes -r -S -m . command to verify duplicate files and their sizes. Compare the compressed and uncompressed distribution contents and identify whether size reductions are feasible; done means a documented, reproducible reduction in distribution size.
