Abort type determination for List early (#9779)

Browse source 
# Description
If we reach the conclusion that the fields of a list are of `Type::Any`
there is no need to continue as the type will remain `Type::Any`

This should improve runtimes of `Value.get_type()` for lists with mixed
types.

# User-Facing Changes
None, a speedup in some cases.

# Tests + Formatting
Relies on existing tests
