Vulkan: LightmapProbes only bake indirect light

[ghost]

Godot version:
master (d0e0a19)

OS/device including version:
NVIDIA GeForce GTX 1060 6GB
Driver 451.48
Windows 10 Home
Backend: Vulkan

Issue description:
LightmapProbes disregard DirectionalLight3Ds, instead baking only indirect light. The lightmap itself does bake DirectionalLight3Ds, however the LightmapProbes that are generated only bake indirect light.

Steps to reproduce:
Create a test scene which contains a BakedLightmap node and meshes with a UV2 channel for lightmap baking. Create a DirectionalLight3D and set its bake mode to Static. View the lightmap probes and see how they only have indirect lighting data and not direct lighting data.

LightmapProbe does not work on the cube ignore in indirect light apparently does not work

Note that this behavior may also be pressent in 3.x. However, in 3.x, lights with the bake mode set to All will light up dynamic objects so that these objects can receive direct light (and receive shadows from other objects, including baked ones).

Edit (January 2022): An equivalent of #41629 was added to master, bringing behavior similar to the paragraph I wrote above. However, dynamic object lighting isn't rendered correctly.

As for baking direct light into lightmap probes, see #73289.
