If a function has lifetime dependencies, disable FSO's dead param optimization. Dead params maybe dependency sources and we should not delete them. It is also problematic to dead code params that are not dependency sources, since lifetime dependent sources are stored as indices and deleting dead parameters will require recomputation of these indices.
`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
The old API will be deprecated in the rebranch.
To avoid merge conflicts, use the new API already in the main branch.

When there are no non-type dead args, DeadArgumentTransform should not
specialize the function. While marking dead type args as not dead, make
sure we go over all the args.
If not, a dead type arg will be attempted to be deleted later on in
FunctionSignatureTransform::DeadArgumentFinalizeOptimizedFunction.
