cleanInvalidSocketPath on start

[GitMensch]

start for existing and invalid debugserver sockets and close those

originally done by @chenhaoyang2019 as a side change in fd7d8ee1642b6e29e84667daefd4083c0771af45 at https://gitee.com/openkylin/native-debug.git

Note: this is not verified at all, I mostly wanted to point this change (and fork, which is published as Kylin Native Debug) out and let others review this in more depth.

The parts that are a bit more complex and relevant "upstream" are:

• assembly debugging (should be mostly fine)
• stdin in debug console, but that seems to be "local linux only" (so may need a bunch of changes)

... and some unrelated changes like editor tab commands to start/stop recording via GDB (which sadly does not work well on most platforms, is very likely gdb-only, and can be enabled/disabled via debug console).

@WebFreak001 Should I rebase and fix the linting issues - or isn't this likely to get merged?

[WebFreak001]

cleaning up at startup sounds like a reasonable idea to me

[GitMensch]

Not sure what the lint-docs want, when I run prettier on that file, I get the exact same result.

[WebFreak001]

issues in CHANGELOG.md?

[WebFreak001]

looks like my version bump was missing a link when I updated the docs - will fix in master

[WebFreak001]

fixed on master now

[GitMensch]

Please recheck the changes, if they look good to you now I'll rebase and merge. Thanks!
