1b83dc2476 *: improve for loop syntax 
Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).

Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

554e48e7b7 compiler: enforce runtime.Notify parameters cast 
If notification parameters type can be defined in a compile time then enforce
parameter cast to the desired type got from manifest.

80f71a4e6e compiler: do not enforce variadic event args check on ellipsis usage 
In case of ellipsis usage compiler defines argument type as ArrayT
(which is correct, because it's a natural representation of the last
argument, it represents the array of interface{}).
Here goes the problem:
```
=== RUN   TestEventWarnings/variadic_event_args_via_ellipsis
    compiler_test.go:251:
        	Error Trace:	compiler_test.go:251
        	Error:      	Received unexpected error:
        	            	event 'Event' should have 'Integer' as type of 1 parameter, got: Array
        	Test:       	TestEventWarnings/variadic_event_args_via_ellipsis
```

Parsing the last argument in this case is a separate complicated problem
due to the fact that we need to grab types of elements of []interface{} inside the
fully qualified ast node which may looks like:
```
runtime.Notify("Event", (append([]interface{}{1, 2}, (([]interface{}{someVar, 4}))...))...)
```

Temporary solution is to exclude such notifications from analysis until we're
able to properly resolve element types of []interface{}.

b57dd2cad6 compiler: properly inline methods, use receiver 
Notice that this doesn't differentiate between (*T) and (T) receivers always
treating them as is. But we have the same problem with arguments now and the
number of inlined calls is limited, usually we want this behavior.

4249674ddc compiler: check for contract permissions 
On many occassions we can determine at compile-time if contract config lacks
some properties it needs. This includes all native contract invocations
through stdlib, as both hashes and methods are known at compile-time
there.

6b3afe9131 compiler: inline all expression with no side-effects, fix #1881 
This has the drawback of traversing expression each time the argument is

The old behaviour can be restored by explicit local assignment.

7577bbef22 compiler: copy locals slice during inline 
Consider function call `f(1, g(2, 3))` when
both `f` and `g` are inlined. If `f` contains some locals,
inlining `g` will replace them with it's another locals map,
because slices in Go reuse storage on `append`.
Thus scope needs to be copied.

b66b853285 compiler: drop stack after inline 
Some control-flow statements drop stack items, for example
`return` when it is used inside of `range` loop.
For inlined calls this `return` should drop only portion of stack
which belongs to inlined call.
