Deprecate and remove usage of aiida.common.utils.strip_prefix

[danielhollas]

Since Python 3.9 this is now equivalent to the str.removeprefix builtin: https://docs.python.org/3.9/library/stdtypes.html#str.removeprefix

❯ rg strip_prefix
src/aiida/common/utils.py
450:def strip_prefix(full_string: str, prefix: str):

src/aiida/orm/utils/node.py
15:from aiida.common.utils import strip_prefix
52:        base_path = strip_prefix(base_path, 'node.')
57:        entry_point_name = strip_prefix(base_path, 'data.')
64:        entry_point_name = strip_prefix(base_path, 'nodes.')
102:        type_string = strip_prefix(type_string, prefix)

src/aiida/restapi/common/identifiers.py
138:    from aiida.common.utils import strip_prefix
154:        base_name = strip_prefix(node_type, data_prefix)
232:        from aiida.common.utils import strip_prefix
237:        full_type = strip_prefix(self._path, 'node.')
242:                    plugin_name = strip_prefix(full_type, basepath)
245:                        plugin_name = strip_prefix(plugin_name, DEFAULT_NAMESPACE_LABEL + '.')

Similarly, I think we can just remove the aiida.common.utils.ArrayCounter. It is not used anywhere, and it's docstring specifically says that it is used in various tests, so I guess we don't need to treat as a stable API?

Since the symbols from aiida.common.utils are not exported at the top level aiida.common I guess it's fine to remove / move stuff. We should just audit this file as a whole, there are a bunch of weird and reaaally specific functions / classes that do not seem general enough to warrant being in this module. For example, functions join_labels and prettify_labels (and the associated Prettifier class) are used only used only in src/aiida/orm/nodes/data/array/bands.py.
