preserve alpha in output buffer (using SrcBlendAlpha = ONE, DstBlendAlpha = ONE_MINUS_SRC_ALPHA consistently
accross all backends), facilitating compositing of the output buffer with another buffer.

- Backends: DX9: Fix to support IMGUI_USE_BGRA_PACKED_COLOR. (#3844) [@Xiliusha]
- Examples: Reworked setup of clear color to be compatible with transparent values.
- CI: Use a dedicated "scheduled" workflow to trigger scheduled builds. Forks may disable this workflow if
scheduled builds builds are not required. [@rokups]
