J. Nick Koston 03eea7bd3f Avoid subprocess memory copy when c library supports posix_spawn (#87958)
* use posix spawn on alpine

* Avoid subprocess memory copy when c library supports posix_spawn

By default python 3.10 will use the fork() which has to
copy all the memory of the parent process (in our case
this can be huge since Home Assistant core can use
hundreds of megabytes of RAM). By using posix_spawn
this is avoided.

In python 3.11 vfork will also be available

https://github.com/python/cpython/pull/11671 but we won't
always be able to use it and posix_spawn is considered safer
https://bugzilla.kernel.org/show_bug.cgi?id=215813#c14

The subprocess library doesn't know about musl though
even though it supports posix_spawn https://git.musl-libc.org/cgit/musl/log/src/process/posix_spawn.c
so we have to teach it since it only has checks for glibc
https://github.com/python/cpython/blob/1b736838e6ae1b4ef42cdd27c2708face908f92c/Lib/subprocess.py#L745

The constant is documented as being able to be flipped here:
https://docs.python.org/3/library/subprocess.html#disabling-use-of-vfork-or-posix-spawn

By default python 3.10 will use the fork() which has to
copy memory of the parent process (in our case
this can be huge since Home Assistant core can use
hundreds of megabytes of RAM). By using posix_spawn
this is avoided and subprocess creation does not
get discernibly slow the larger the Home Assistant
python process grows.
