Rework usages/naming of configuration macros [part 2] (#2903)

There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.

Main changes:

* The following macros are now 0/1 switches:
** Renamed CONFIG_ECMA_LCACHE_DISABLE to JERRY_LCACHE.
** Renamed CONFIG_ECMA_PROPERTY_HASHMAP_DISABLE to JERRY_PROPERTY_HASHMAP.
** Renamed CONFIG_DISABLE_UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
** Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
** Renamed JERRY_DISABLE_JS_PARSER to JERRY_PARSER.
** Renamed JERRY_ENABLE_ERROR_MESSAGES to JERRY_ERROR_MESSAGES.
** Renamed JERRY_ENABLE_EXTERNAL_CONTEXT to JERRY_EXTERNAL_CONTEXT.
** Renamed JERRY_ENABLE_LINE_INFO to JERRY_LINE_INFO.
** Renamed JERRY_ENABLE_LOGGING to JERRY_LOGGING.
** Renamed JERRY_ENABLE_SNAPSHOT_EXEC to JERRY_SNAPSHOT_EXEC.
** Renamed JERRY_ENABLE_SNAPSHOT_SAVE to JERRY_SNAPSHOT_SAVE.
** Renamed JERRY_SYSTEM_ALLOCATOR to JERRY_SYSTEM_ALLOCATOR.
** Renamed JERRY_VM_EXEC_STOP to JERRY_VM_EXEC_STOP.
** Renamed JMEM_GC_BEFORE_EACH_ALLOC to JERRY_MEM_GC_BEFORE_EACH_ALLOC.
** Renamed JMEM_STATS to JERRY_MEM_STATS.
** Renamed PARSER_DUMP_BYTE_CODE to JERRY_PARSER_DUMP_BYTE_CODE.
** Renamed REGEXP_DUMP_BYTE_CODE to JERRY_REGEXP_DUMP_BYTE_CODE.
* Recursion check changes:
** Renamed REGEXP_RECURSION_LIMIT to JERRY_REGEXP_RECURSION_LIMIT.
** Renamed VM_RECURSION_LIMIT to JERRY_VM_RECURSION_LIMIT.
* Attribute macro changes:
** Renamed JERRY_CONST_DATA to JERRY_ATTR_CONST_DATA.
** Renamed JERRY_HEAP_SECTION_ATTR to JERRY_ATTR_GLOBAL_HEAP.
  Now the macro can specify any attribute for the global heap object.
* Other macro changes:
** Renamed CONFIG_MEM_HEAP_AREA_SIZE to JERRY_GLOBAL_HEAP_SIZE.
   Then new macro now specify the global heap size in kilobytes.
* Updated documentations to reflect the new macro names.
