[WIP] Enable init values for Object FIFO

[AndraBisca]

This PR builds on top of #1801 to enable objectfifos to take as input an array of initial values.

Specifically:

• initial values should be of the MLIR type ElementsAttr,
• the above should also be of the same memref type as the objectfifo type,
• the initial values array should be of the same size as the depth of the objectfifo,
• the objectfifo lowering is modified to generate AIE_LockOps with init values such that the initialized objects will not be overwritten before they are communicated to the consumer(s).
