Log message:
Mass-change BUILD_DEPENDS to TOOL_DEPENDS outside mk/.

Almost all uses, if not all of them, are wrong, according to the
semantics of BUILD_DEPENDS (packages built for target available for
use _by_ tools at build-time) and TOOL_DEPEPNDS (packages built for
host available for use _as_ tools at build-time).

No change to BUILD_DEPENDS as used correctly inside buildlink3.

importlib_metadata is a library which provides an API for accessing an
installed package's metadata, such as its entry points or its top-level name.
This functionality intends to replace most uses of pkg_resources entry point
API and metadata API. Along with importlib.resources in Python 3.7 and newer
(backported as importlib_resources for older versions of Python), this can
eliminate the need to use the older and less efficient pkg_resources package.

importlib_metadata is a backport of Python 3.8's standard library
importlib.metadata module for Python 2.7, and 3.4 through 3.7. Users of Python
3.8 and beyond are encouraged to use the standard library module, and in fact
for these versions, importlib_metadata just shadows that module. Developers
looking for detailed API descriptions should refer to the Python 3.8 standard
library documentation.

This package contains the last version supporting python 2.7.
