Allow more flexible adjustments of VisualInstance3D Lightmap Scale

Browse Source 
Any floating-point value greater than 0.01 can now be used.
Prior to this change, only factors of 1×, 2× and 4× and 8× could be used.

The texel density to use for lightmapping in [LightmapGI]. Greater scale values provide higher resolution in the lightmap, which can result in sharper shadows for lights that have both direct and indirect light baked. However, greater scale values will also increase the space taken by the mesh in the lightmap texture, which increases the memory, storage, and bake time requirements. When using a single mesh at different scales, consider adjusting this value to keep the lightmap texel density consistent across meshes.
For example, doubling [member gi_lightmap_texel_scale] doubles the lightmap texture resolution for this object [i]on each axis[/i], so it will [i]quadruple[/i] the texel count.

<constant name="GI_MODE_DYNAMIC" value="2" enum="GIMode">
Dynamic global illumination mode. Use for dynamic objects that contribute to global illumination. This GI mode is only effective when using [VoxelGI], but it has a higher performance impact than [constant GI_MODE_STATIC]. When using other GI methods, this will act the same as [constant GI_MODE_DISABLED]. When using [LightmapGI], the object will receive indirect lighting using lightmap probes instead of using the baked lightmap texture.
