This patch adds support for `float8_e3m4` and `float8_e4m3` in
`np_to_memref.py` by adding the appropriate ctypes structures.
Additionally changes minimum numpy version to 2.1.0 and uses a single
ml_dtypes version of 0.5.0.
This patch makes the premerge advisor write out comments. This allows
for surfacing the findings of the advisor in a user-visible manner
beyond just dumping the output in the logs. Surfacing the information in
a comment also makes it much easier to discover compared to the Github
summary view.

This a reland of https://github.com/llvm/llvm-project/pull/155741 which
was reverted at https://github.com/llvm/llvm-project/pull/157831. This
version is narrower in scope - it only turns on automatic stub
generation for `MLIRPythonExtension.Core._mlir` and **does not do
anything automatically**. Specifically, the only CMake code added to
`AddMLIRPython.cmake` is the `mlir_generate_type_stubs` function which
is then used only in a manual way. The API for
`mlir_generate_type_stubs` is:
```
Arguments:
MODULE_NAME: The fully-qualified name of the extension module (used for importing in python).
DEPENDS_TARGETS: List of targets these type stubs depend on being built; usually corresponding to the
specific extension module (e.g., something like StandalonePythonModules.extension._standaloneDialectsNanobind.dso)
and the core bindings extension module (e.g., something like StandalonePythonModules.extension._mlir.dso).
OUTPUT_DIR: The root output directory to emit the type stubs into.
OUTPUTS: List of expected outputs.
DEPENDS_TARGET_SRC_DEPS: List of cpp sources for extension library (for generating a DEPFILE).
IMPORT_PATHS: List of paths to add to PYTHONPATH for stubgen.
PATTERN_FILE: (Optional) Pattern file (see https://nanobind.readthedocs.io/en/latest/typing.html#pattern-files).
Outputs:
NB_STUBGEN_CUSTOM_TARGET: The target corresponding to generation which other targets can depend on.
```
Downstream users should use `mlir_generate_type_stubs` in coordination
with `declare_mlir_python_sources` to turn on stub generation for their
own downstream dialect extensions and upstream dialect extensions if
they so choose. Standalone example shows an example.
Note, downstream will also need to set
`-DMLIR_PYTHON_PACKAGE_PREFIX=...` correctly for their bindings.
This PR turns on automatic type stub generation (rather than relying on
hand-written/updated stubs). It uses nanobind's [stubgen
facility](https://nanobind.readthedocs.io/en/latest/typing.html#stub-generation).
If you would like to enable this functionality you can add
`GENERATE_TYPE_STUBS` to `declare_mlir_python_extension` .
This patch adds a new script with the ability to upload/download
.lit_test_times.txt files to ensure tests are run in a reasonably
optimal order.
The plan is to integrate this into the workflows in follow-up PRs.
The CI scripts install some python dependencies primarily for testing
this patch moves these over to a single requirements file that also hash
pins everything using pip-compile to conform to best security and
reproducibility practices.
