This commit adds to ID struct a new optional 'weak reference' to a linked ID (in the form of a blend file library path and full ID name). This can then be used on next append to try to find a matching local ID instead of re-making the linked data local again. Ref. T90545 NOTE: ID re-use will be disabled for regular append for the time being (3.0 release), and only used for assets. Therefore, this commit should not change anything user-wise.
