Related to #4186.
Some notable changes:
- The term 'Error' now strictly refers to native Error objects defined in
the ECMA standard, which are ordinary objects. All other uses of
'error' or 'error reference' where the term refers to a thrown value is
now called 'exception'.
- Simplified the naming scheme of many String API functions. These functions
will now also take an 'encoding' argument to specify the desired
encoding in which to operate.
- Removed the substring-copy-to-buffer functions. These functions
behaved awkwardly, as they use character index to specify the
start/end positions, and were mostly used incorrectly with byte
offsets instead. The functionality can still be replicated with
other functions if necessary.
- String-to-buffer functions will no longer fail if the buffer is not
sufficiently large, the string will instead be cropped.
- Fixed the usage of the '_sz' prefix in many API functions. The term
'sz' means zero-terminated string in hungarian notation, this was
used incorrectly in many cases.
- Renamed most of the public API functions to have shorter, more on-point
names, rather than the often too long descriptive names. Functions are now
also grouped by the type of value they operate on, where this makes
sense.

including those which are created by an eval call.

This information is stored in a separate memory block instead
of being part of the byte code. Snapshot does not supported.

The removal of these macros enabled cppcheck to reveal new errors.
These errors are also fixed by the patch.

- Type for realm objects is introduced (ecma_global_object_t)
- Realm reference is added to built-in objects and ECMAScript functions
- Resolving built-ins, global environments, and scopes require realm object
- Unnecessary global object accesses are removed from the code
Missing: external functions and static snapshot functions have no realm reference

Now the following conventions are applied:
- passing the number of arguments for a function call is always uint32_t
- string size/length/position related operation should use lit_utf8_size_t
- Extended objects internal fields must be uint32_t

In ES2015 many builtin prototypes are no longer valid instances of their
respective classes. This change updates affected prototypes to be
regular objects as required.
