e8ec820d2e vm: add unload command 
When execution fails it's the only way to change the prompt showing the
last executed instruction. Example:

```
NEO-GO-VM > loadgo examples/engine/engine.go
READY: loaded 117 instructions
NEO-GO-VM 0 > run
Error: at instruction 3 (SYSCALL): failed to invoke syscall 805851437: syscall not found
NEO-GO-VM 8 > parse
Error: missing argument
NEO-GO-VM 8 > parse 123
Integer to Hex			7b
Integer to Base64		ew==
String to Hex			313233
String to Base64		MTIz

NEO-GO-VM 8 > unload
NEO-GO-VM > exit

```

These tests are slow on Windows, so refactor them a bit and avoid the following
error:

ad65d1fa1f compiler: implement custom logic for go1.15 
For some reason `foo.go` is interpreted as an http URL, and even if we
replace it with `./foo.go` there is an errors with file missing on disk.
Because `CompileWithOptions` should be able to compile file under any
circumstances, we allocate temporary directory base on version used to
compile a binary.

e7a0ecb349 compiler: provide .go filename to Compile 
First argument contains filename, thus we use '.go' suffix to
distinguish between directories and files.
Contract name should be provided in options.

8af9c870b1 compiler: remove CompileWithDebugInfo 
It is a simple wrapper over `CompileWithOptions` which we don't really
need. Custom options can be specified explicitly instead of using some
random default. This default was introduced in 1578904da, however tests
written there use `CompileWithOptions` and all other tests
pass on that commit even without this default.
