  [MLIR][Bufferization] Fix out-of-bounds access in setInPlaceOpOperand (#186280)

When annotating operations with bufferization markers during analysis,
setInPlaceOpOperand reads the existing __inplace_operands_attr__ and
then sets one entry. If the attribute was provided by the user with
fewer entries than the op has operands (e.g. a return with two tensor
operands but only one entry in the annotation), the function would crash
with an out-of-bounds vector access.

Fix by resizing the vector to the actual operand count before setting
the entry when the existing annotation is too short.

Fixes #128316
