Now __getitem__ can pick items in the transitive link/run graph,
or from direct build dependencies.

This commit changes the model to treat compilers as nodes, and
drops the concept of a "compiler" as a bundle of a C, C++, and
Fortran compiler.
Implementation does not rely on `Compiler` or `CompilerSpec`.
This reverts commit 2c47dddbc1.
Now, `spack compiler` writes by default in packages.yaml. Entries
in old `compilers.yaml` are converted to external specs as a way to
support legacy configuration.
Since this operation is expensive, an environment variable can be
used to enforce the deprecation of `compiler.yaml`.
The --mixed-toolchain option has been deprecated, since it stops to
make sense once compiler are treated as nodes.
On Windows, libraries search their directory for dependencies, and
we help libraries in Spack-built packages locate their dependencies
by symlinking them into the dependent's directory (we refer to this
as simulated RPATHing).
We extend the convenience functionality here to support base library
directories outside of the package prefix: this is primarily for
running tests in the build directory (which is not located inside
of the final install prefix chosen by spack).
Python was removed from being a build tool in #46980, due to issues
when reusing specs. This PR adds a new rule to match the interpreter
among different Python packages, in clingo.
It also adds a bunch of new "build-tools", so that specs like:
```
py-matplotlib backend=tkagg
```
can be concretized in one go.
Modifications:
- [x] Make `py-matplotlib backend=tkagg` concretizable
- [x] Add unit-tests to ensure situations like in #46980 do not happen

Currently, the custom config scopes are pushed at the top when constructing
configuration, and are demoted whenever a context manager activating an
environment is used - see #48414 for details. Workflows that rely on the order
in the [docs](https://spack.readthedocs.io/en/latest/configuration.html#custom-scopes)
are thus fragile, and may break
This PR allows to assign priorities to scopes, and ensures that scopes of lower priorities
are always "below" scopes of higher priorities. When scopes have the same priority,
what matters is the insertion order.
Modifications:
- [x] Add a mapping that iterates over keys according to priorities set when
adding the key/value pair
- [x] Use that mapping to allow assigning priorities to configuration scopes
- [x] Assign different priorities for different kind of scopes, to fix a bug, and
add a regression test
- [x] Simplify `Configuration` constructor
- [x] Remove `Configuration.pop_scope`

All the build jobs in pipelines are apparently relying on the bug that was fixed.
The issue was not caught in the PR because generation jobs were fine, and
there was nothing to rebuild.
Reverting to fix pipelines in a new PR.
This reverts commit 3ad99d75f9.
VariantMap.concrete is unused, and would be incorrect if it were used
due to conditional variants.
Just let the Spec dictate what is concrete and what is not.
