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.

During the execution of the TypedArray filter method it is possible
to have a different sized output TypedArray than the input one.
When copying the data to the output array the values must be
correctly converted to the output TypedArray's value range.
Fixes: #4793

When executin the TypedArray's slice method it is possible to have
the a different element sized output TypedArray. In such case
the data must be converted to the desired element type/size.

In the Array.slice method when the engine uses fast arrays the "end" value
was not updated if the input array's length changed. This can occur when the start/end
index normalization executes a method and the length is changed forcefully.
This leads to a buffer-overflow as the element copy reads too much data from the input
array.

We don't need to check arguments length inside the custom dispatchers,
because we have already checked within ecma_bultin_dispatch_routine.

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