Merge workflows and update issue template

[Darvisim]

• Merged all workflow files like build-linux.yml, build-macos.yml and others into a single workflow file main.yml.
• Updated issue templates by replacing the .md files with the .yml files.

Merged all workflow files like build-linux.yml, build-macos.yml and others into a single workflow file main.yml.

Please explain the rationale behind this, for me it does not make the maintenance any easier. Platforms are different enough to deserve a different config. @Novum thoughts ?

In my opinion, it is more convenient to configure the platforms via their dedicated jobs rather than separate workflows. Hence, I merged them into a single file. However, I am uncertain how this would affect maintenance. Wouldn't it be more efficient to maintain one workflow file compared to maintaining workflow files for each platform?

Sorry the .yaml bug template format do not work, and I'm not intrested in the other main.yml. And frankly this subject do not interest me enough compared to the free time I have. Thanks anyway.
