The previous `ecma_is_constructor` implementation did not checked if the
target function was an arrow or generator function. This resulted in
an incorrect execution for these function types.

The `IsCallable(target)` and `IsConstructor(target)` info
can't be stored in the target/handler values.
If the input for the ProxyCreate was a revocable Proxy the original target's
callable/constructor information must be retained even after the
Proxy was revoked.

With a disabled JERRY_BUILTIN_PROXY option the build fails becouse
of missing guards.
The run-test buildoption_test is also extended with this.

- Store arguments in a register when possible
- Create separate arguments object for function argument initializer when necessary

- External ArrayBuffer construction with 0 length should be equivalent to `new ArrayBuffer(0)`
- Internally allocated ArrayBuffers should be detachable
- Externally allocated ArrayBuffers free callback should be called when underlying buffer is detached

Member variables of the object must be initialized before setting the
required flags, otherwise the uninitalized values can cause problems
during garbage collection.

In the newer ecma262 standard (post ES11) the ProxyCreate was
changed and the revoked Proxy handler/target is not checked.

We do not support the caller information for functions, and since a
'null' value represents that there has been no caller, the default value
should be changed to 'undefined' to signal that the information is not
available.

- Enhancement: Arguments object properties are now lazy instantiated
- Bugfix: Mapped arguments object instantiated properties cannot be lcached
- Bugfix: Mapped arguments should be constructed even if 0 formal parameters or arguments are provided
- Update: remove 'caller' property of unmapped arguments object

A new shared frame context data is created which allows sharing
data between the function call and vm main loop. Furthermore
rest arguments and current function object handling is reworked.

If the prototype of a fast array is changed, for example to a Proxy object,
the array should be converted back to a normal array. This is required to
correctly handle any [[Get]]/[[Set]]/etc... calls which should trigger
these method calls on the before mentioned Proxy object.
