  Log Message:
  -----------
  [mlir][linalg][bufferize] Store analysis results in BufferizationAliasInfo

* Store inplace bufferization decisions in `inplaceBufferized`.
* Remove `InPlaceSpec`. Use a bool instead.
* Use `BufferizableOpInterface::bufferizesToWritableMemory` and `bufferizesToWritableMemory` instead of `getInPlace(BlockArgument)`. The analysis does not care about inplacability of block arguments. It only cares whether the buffer can be written to or not.
* The `kInPlaceResultsAttrName` op attribute is for testing purposes only.

This commit further decouples BufferizationAliasInfo from other dialects such as SCF.
