compiler: check for pkg nilness, fix #3202
...
Unfortunately, when import cycle happens somewhere deep in the import chain we
dont't get an error from packages.Load(). But it leaves some imports
uninitialized, so at least we can check for them.

compiler: rename named unused global vars to "_"
...
So that (*codegen).Visit is able to omit code generation for these
unused global vars. The most tricky part is to detect unused global
variables, it is done in several steps:
1. Collect the set of named used/unused global vars.
2. Collect the set of globally declared expressions that contain
function calls.
3. Pick up global vars from the set made at step 2.
4. Traverse used functions and puck up those global vars that are used
from these functions.
5. Rename all globals that are presented in the set made at step 1
but are not presented in the set made on step 3 or step 4.

compiler: emit code for unnamed global var decls more careful
...
In case if global var is unnamed (and, as a consequence, unused) and
contains a function call inside its value specification, we need to emit
code for this var to be able to call the function as it can have
side-effects. See the example:
```
package foo
import "github.com/nspcc-dev/neo-go/pkg/interop/runtime"
var A = f()
func Main() int {
return 3
}
func f() int {
runtime.Notify("Valuable notification", 1)
return 2
}
```

compiler: use absolute paths for debug data
...
It's not a perfect thing, but neo-debugger just doesn't work at all with
relative pathes. Notice that `saveSequencePoint` still used absolute ones
leading to invalid debug.json data, but fixing it there doesn't help,
neo-debugger can't load source code using relatives.

compiler: set type information during traversal, fix #2231
...
Set all necessary context before file traversal, not only import
maps. Also, we can skip restoring import maps because all our code is
processed via `For*` iterators which set necessary context.
We can also refactor this a bit to have all context in one place,
this will be done in #2086 .
