Enable JXL support in linux builds

[emkw]

Description

I propose to add JXL support for linux builds; the recently released linux build doesn't support it.
Unfortunately I don't know how to make a test build, so I'm not sure if it builds correctly.

All submissions

• there are no other open Pull Requests for the same update/change
• Bromite can be built with these changes
• I have tested that the new change works as intended (AVD or physical device will do)

Format

• patch subject and filename match (e.g. Subject: Alternative cache (NIK-based) -> Alternative-cache-NIK-based.patch)
• patch description contains explanation of changes
• no unnecessary whitespace or unrelated changes

Adding enable_jxl_decoder=true to gn args could do it without changing the patch.

I'd like you to try, I can help you it's simple, will you?

it's simple

But it's computationally intensive :)

enable_jxl_decoder=true Cromite left, ungoogled-chromium without jxl support right:

mah, I think a good machine today is capable, and I think it is capable even while using the PC for something else, just adjust the number of threads to suit your needs.
it is only a matter of time, and space, that yes, but who doesn't have 100gb available :)
anyone can try the cromite build with three simple steps (and I would like to know the times according to the configurations :)

That might pose a problem as I'm on low spec CPU

I would like to know the times according to the configurations

It takes almost 16 hours on E3-1246 v3 @ 3.50GHz

Correct, on Linux one could adjust process "niceness" to lower its priority for computer resources.

I preferred this one #665 (comment), added directly in cromite.gn_args
