During ecma_collection_append the underlying collection
was not increased in the required case. This triggered
a buffer overflow when processing the bound function's arguments
during call or during the Proxy ownKeys method.

Until now JERRY_CONTEXT_INVALID_NEW_TARGET was used to represent whether the eval called from the script directly.
This information can be retrieved from the parser, so it simplifies the runtime handling of the new.target.
This patch fixes#3630, fixes#3640 and fixes#3641.

Currently, collections use object based solutions for storing elements and
iterating on them. If an element is deleted and re-inserted, the storage
position is the same as before so the iteration order is wrong.
This patch replaces the object based storage with an array based solution
that helps to store and iterate elements as expected.

Changes:
- Use the pre-scanner to provide information for the parser about the existence of the class constructor
- The allocation of the super declarative environment is no longer needed
- The VM frame context holds the information about the this binding status
- Reduce the number of class related VM/CBC instructions
- Improve ecma_op_function_{construct, call} to properly set new.target

This change fixes the handling of lexical blocks when executing multiple
scripts, and also fixes a few issues with module environments.
After this change, all script files will run in the same context and
will have access to lexically scoped global variables of previous
scripts, and module environments will no longer have a bound global
'this' value.
The REPL implementation in main-unix is also fixed to correctly handle
lexically scoped variables.
Fixes#3561.

The `jerry_objects_foreach` and `jerry_objects_foreach_by_native_info` methods

which should only be used internally thus these objects should not be accessed

The ecma_number_to_uint32 function is called many times, we can merge

There is no reason to force the developer to call ecma_number_is_nan
check before all ecma_number_is_zero and ecma_number_is_infinity.
These functions work fine and return false if NaN is passed.

This change cleans up object deallocation, and reorganizes the code so
that we are able to do object type specific operations before the
properties are freed.
Previously this would require extra conditions that would slow things
down regardless of object type. With this change however, object type
conditions are checked only once for each possible type.
