Add support for electron v43 prebuilds

[m4heshd]

Prebuilds were tested on Windows. But would love to test all with #1487.

[neoxpert]

Compiled and ran basic tests on Linux (Arch) and MacOS (26.5.2).

@neoxpert Thank you

[m4heshd]

@neoxpert Build failing on Linux. Can you check your compiler setup against the ones from the containers in the build script?

[neoxpert]

I guess that the used gcc-12 in the node20:bookworm container has trouble with properly resolving the macros used in the v8 headers. I'll have a deeper look tomorrow, but we might need to change the used Debian / gcc version or extend the build script.

[m4heshd]

Perfect. Lemme know. Also, @JoshuaWise, can we please merge #1487? There's no other easy way to test it all locally.

So it looks like gcc-12, which ships with bookworm, is "too old". After testing several setups using the node images, there are several options to counter the failed build.

• We could either lift the image for the modern Electron builds to trixie, which has gcc-14. This might lead to new issues due to libc version conflicts on target systems.
• We could go down the road of building gcc-13 within the bookworm container (which would take some time ...) or inject a prebuilt version as it is not available within the bookworm repo.
• Introduce another new step for electron to build everything beginning with 43.0.0 with trixie while continue building the old versions in the bookworm container ..
