Macro for Loading Internal Binary Assets (#6478)

Browse Source 
# Objective

The `load_internal_asset` macro is helpful when creating rendering plugins, but it doesn't support load binary assets (like those compiled as spir-v).

## Solution

Add a `load_internal_binary_asset` macro that use `include_bytes!`.
