Part of Code Quality Project outlined in #130975. This patch eschews warning messages urging the user to "select all related strips" when copying or creating new metastrips and instead automatically includes those related strips in the operation. - Attempting to copy or create a metastrip with no strips selected no longer delivers a warning. - When copying strip(s), if there are related effect chains, they will be automatically selected and included in the copy if the operation succeeds. - The decision to select related strips was intentional, as it allows the user to easily see the entire effect chain and thus which strips were copied. - When creating a new metastrip, if there are related effect chains, they will automatically be included in the resulting metastrip. - This is done using a new `SEQ_query_strip_connected_and_effect_chain()` iterator. This iterator is only used for metastrips, and not copying, since the user may wish to only copy single strips in a connection, but connected strips should always stay together in a metastrip/seqbase.
