Remove --global-option and --build-option flags

-## Customising the build

-The `--global-option` and `--build-option` arguments to the `pip install`
-and `pip wheel` inject additional arguments into the `setup.py` command
-(`--build-option` is only available in `pip wheel`).
-
-```{attention}
-The use of `--global-option` and `--build-option` is highly setuptools
-specific, and is considered more an accident of the current implementation than
-a supported interface. It is documented here for completeness. These flags will
-not be supported, once this build system interface is dropped.
-```
-
-These arguments are included in the command as follows:
-
-```
-python setup.py <global_options> BUILD COMMAND <build_options>
-```
-
-The options are passed unmodified, and presently offer direct access to the
-distutils command line. For example:
-
-```{pip-cli}
-$ pip wheel --global-option bdist_ext --global-option -DFOO wheel
-```
-
-will result in pip invoking:
-
-```
-setup.py bdist_ext -DFOO bdist_wheel -d TARGET
-```
-
-This passes a preprocessor symbol to the extension build.

-```{danger}
-This disables the use of wheels (cached or otherwise). This could mean that builds will be slower, less deterministic, less reliable and may not behave correctly upon installation.
-
-This mechanism is only preserved for backwards compatibility and should be considered deprecated. A future release of pip may drop these options.
-```
-
-The `--global-option` option is used to pass options to `setup.py`.
-
-```{attention}
-These options are highly coupled with how pip invokes setuptools using the {doc}`../reference/build-system/setup-py` build system interface. It is not compatible with newer {doc}`../reference/build-system/pyproject-toml` build system interface.
-
-This is will not work with other build-backends or newer setup.cfg-only projects.
-```
-
-If you have a declaration like:
-
-    FooProject >= 1.2 --global-option="--no-user-cfg"
-
-The above translates roughly into running FooProject's `setup.py` script as:
-
-    python setup.py --no-user-cfg install
-
-Note that the only way of giving more than one option to `setup.py` is through multiple `--global-option` options.
