Introduction of portaudio/19.7.0 and fix for vulkan-loader/1.3.239.0 for conan 2.0

There are two items in this pull request:

Introduction of the portaudio/19.7.0 recipe for conan 2.x
fixes #16335
Following our discussion with @Croydon on #16335 I have made the following further modifications to it:

• I have restored the default options the recipe had on bincrafters (both alsa and jack options are now set to true by default)
• Since I have not managed to get the conancenter's libalsa package to produce sound on linux since 2021 (please see [package] libalsa/1.1.9 & libalsa/1.2.5.1: No devices listed via portaudio #7526) and I have not been able to fix it myself, I have removed the "hacky" option I had originally implemented to allow its use from this portaudio package (please also see Portaudio 19.7.0 fixes: invalid device error and mingw gcc build bincrafters/community#1419) and have completely removed the libalsa conancenter requirement from portaudio. The portaudio package now uses the linux system alsa package now (installed by apt or yum). I understand that this is less than ideal but please note that the conancenter libalsa problem has been around for a long time, not allowing the portaudio package to ever produce sound on Linux, at least on my end whenever I have tried to use it. The solution in this pull request has allowed me to use the portaudio package (this variation I am submitting originally copied from bincrafters), playing sound on Linux on many machines without issue. It might be worth adding it to conancenter as is, so that others can also benefit from it. (I would not mind making other improvements to the recipe though, appart from re-adding conancenter's alsa requirement)

Minor fix for the vulkan-loader/1.3.239.0 package for conan 2.x
fixes #16358

I understand that this pull request may be rejected, based on past discussions, but I thought to submit my potential contributions anyway, in case they prove useful either by integration into the cci repository, or at least as information that can be used in improvements implemented by others.

Sorry @spacelm, I have just realised how you have addressed the VS issue in your vulkan-loader pull request. I hadn't found your correction for that particular bit before. And about portaudio I didn't have much hope that my version would be accepted after discussing with @Croydon anyway so I am withdrawing this whole pull request.
