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.

Function arguments must be passed as string values.
Snapshots are generated from compiled code rather than source code.

The same data is returned for the script and all of its functions,
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 function declarations in jerryscript-core.h should not be visible
internally, only the type declarations in jerryscript-types.h

`obj[number]` is a widely used structure especially for array element indexing, however super property assignment is not.
This patch moves super-assignment opcodes to ext opcodes and fills the freed 3 basic opcodes with push-literal-number ones.

- 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

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.

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.

Only parsing is implemented, so the async functions currently behave
like normal function except they return with a resolved Promise object
when the function is terminated correctly.

There is no need for a specific opcode after yield because
the return and throw commands can be redirected to fake byte code sequences.
