Intel acceleration fails for projects that link/dlopen libvpl

📌 Task summary

Install libvpl2 for all Intel branches

📋 Task details

_setup_intel_arc() installs libvpl2 on debian, but not on ubuntu, and _setup_intel_modern() installs libvpl2 on neither. This causes runtime failures with anything that tries to load the library (e.g. ErsatzTV's next streaming engine that uses libvpl for capability detection https://github.com/ErsatzTV/next/blob/main/crates/ffpipeline/src/capabilities/qsv/vpl.rs).

A fresh install of ErsatzTV with acceleration enabled on an N150 gives this error when troubleshooting playback using the next streaming engine:

[08:40:49 Error] [ersatztv_channel::config] failed to probe QSV capabilities: error detecting qsv capabilities: libvpl not found: dlopen failed

Fix is simply apt -y install libvpl2. Then it results in:

[08:53:32 Debug] [ersatztv_channel::config] detected QSV capabilities: QsvCapabilities { supported_decoders: {H264: [8], Vc1: [8], Vp8: [8], Mpeg2Video: [8], Hevc: [8, 10], Av1: [8, 10], Vp9: [8, 10]}, supported_encoders: {Mpeg2Video: [8], H264: [8], Vp9: [8, 10], Hevc: [8, 10]}, vpp_pixel_formats: {"RGB4", "Y210", "RG10", "RGB2", "Y216", "AYUV", "P010", "RGBP", "NV12", "Y416", "BGRP", "BGR4", "Y410", "YUY2", "P016"} }
