Objective

Currently, it is quite awkward to use the pbr function in a custom shader without binding a mesh bind group.
This is because the pbr function depends on the MESH_FLAGS_SHADOW_RECEIVER_BIT flag.

Solution

I have removed this dependency by adding the flag as a parameter to the PbrInput struct.

I am not sure if this is the ideal solution since the mesh flag indicates both MESH_FLAGS_SIGN_DETERMINANT_MODEL_3X3_BIT and MESH_FLAGS_SHADOW_RECEIVER_BIT.
The former seems to be unrelated to PBR. Maybe the flag should be split.

Spelling nit for the title: singular is "dependency" in English :)

Remove dependency on the mesh struct in the pbr function (#7597)

# Objective

Currently, it is quite awkward to use the `pbr` function in a custom shader without binding a mesh bind group.
This is because the `pbr` function depends on the `MESH_FLAGS_SHADOW_RECEIVER_BIT` flag.

## Solution

I have removed this dependency by adding the flag as a parameter to the `PbrInput` struct.

I am not sure if this is the ideal solution since the mesh flag indicates both `MESH_FLAGS_SIGN_DETERMINANT_MODEL_3X3_BIT` and `MESH_FLAGS_SHADOW_RECEIVER_BIT`.
