"* Shared Library {A,UB}SAN Enterprise RHEL 8.0 DEBUG (all feature flags)" and "* {A,UB}SAN Enterprise RHEL 8.0 DEBUG (Classic Engine)" variants do not compile for themselves and re-uses compiled binaries from "! Linux x86 Shared Library {A,UB}SAN Enterprise Compile" variant.

However those variants are running "generate_buildid_to_debug_symbols_mapping" tasks, which tries to upload the same data to symbolizer service and gives service additional strain unnecessarily. Example from a single evergreen version:

• task on "! Linux x86 Shared Library {A,UB}SAN Enterprise Compile" variant
• task on "* Shared Library {A,UB}SAN Enterprise RHEL 8.0 DEBUG (all feature flags)" variant
• task on "* {A,UB}SAN Enterprise RHEL 8.0 DEBUG (Classic Engine)" variant

We can remove "generate_buildid_to_debug_symbols_mapping" tasks from "* Shared Library {A,UB}SAN Enterprise RHEL 8.0 DEBUG (all feature flags)" and "* {A,UB}SAN Enterprise RHEL 8.0 DEBUG (Classic Engine)" variants without losing any data.
