* Optimize vis_heap_chunks command
This commit optimizes the vis_heap_chunks command by:
1) precalculating bin labels instead of computing them on demand for each chunk
2) calling pwndbg.gdblib.memory.read once instead of twice in a hot loop
For `vis 2000` command ran when debugging python3 shell, the first change
cut down the execution time from almost 20s to 5s.
Another benchmark, for both 1) and 2) changes showed 19.28s->4.14s timing.
The benchmark done is included in this commit in
profiling/benchmark_vis_heap_chunks/ so that it can be reproduced e.g.
to optimize the function further or to reproduce my results.

Technically Arch Linux ARM is a separate distro from the x86_64 Arch Linux, but it uses pcaman and the same package names. So it installs just fine, just needs to be detected properly.
* feature: Add `killthreads` command (closes#1580)
This command allows the user to quickly kill multiple threads by
specyfying their ids as arguments to this command. It also supports
the `--all` flag, which will kill overy thread except the currently
selected one. This is useful for use with the `checkpoint` command.
The killing is done by calling `pthread_exit(0)`.
* fix: try fixing building test binaries by enabling -lpthread
* fix: remove error message check when calling pthread_exit
Removed the message check, because the error messages difffer between
versions of GDB.
* fix: Improve UX of the killthreads command
Add an extended description of the command, some validation on the thread IDs
and suppress GDB output.
* fix: lint
* fix: put the multiline help text in the correct place
* tests: fix test failing due to a race condition when running in parrallel to other tests
Replaced asserts with loops which wait for a cundition to be met, so that the tests doesn't fail due to scheduling issues.
* tests: add more fixes for race conditions in test_killthreads
* fix: lint
* Update pwndbg/commands/killthreads.py
* tests: Wait for exactly three threads

Now the installation process contains the following steps:
1. Check for any line with source <gdbinit.py> before installation
2. If any, ask the user if they want to proceed
3. After the installation, comment out old source <gdbinit.py> lines if any and add a new source <gdbinit.py> line.
A check for presence of the line set debuginfod enabled on is also added to avoid being appended repeatedly.
* Add largebin reverse lookup tables
