syl20bnr 584392bd92 [core] Fix layer dependencies based on layer variables
There was a edge case with the declaration of the `lsp` layer in `layers.el`
files.
The `hy` layer depends on the `python` layer which in turn depends on the `lsp`
layer if and only if the `python-backend` layer variable is set to `lsp`.
When the `hy` layer was declared first then it declares the `python` layer
without its layer variables, thus the `lsp` layer was not declared because the
`python-backend` variable was not set.

The fix is to gather all the layer dependencies and resolve them only after all
the used layers have been declared.

* new function `configuration-layer/declare-layer-dependencies`
* replace all calls to `configuration-layer/declare-layer` by the new function
  except for distribution layers (we declare layer dependencies right away in
  distribution layers)
