Rebase onto llvm-project f69328049e9e with local changes

This commit rebases the compiler onto commit f69328049e9e from
llvm-project.

Changes:

* Use of the one-shot bufferizer for improved memory management

* A new pass `OneShotBufferizeDPSWrapper` that converts functions
  returning tensors to destination-passing-style as required by the
  one-shot bufferizer

* A new pass `LinalgGenericOpWithTensorsToLoopsPass` that converts
  `linalg.generic` operations with value semantics to loop nests

* Rebase onto a fork of llvm-project at f69328049e9e with local
  modifications to enable bufferization of `linalg.generic` operations
  with value semantics

* Workaround for the absence of type propagation after type conversion
  via extra patterns in all dialect conversion passes

* Printer, parser and verifier definitions moved from inline
  declarations in ODS to the respective source files as required by
  upstream changes

* New tests for functions with a large number of inputs

* Increase the number of allowed task inputs as required by new tests

* Use upstream function `mlir_configure_python_dev_packages()` to
  locate Python development files for compatibility with various CMake
  versions
