Concurrently accessing internal external uncached strings is not
thread-safe. We are removing a case where we can make such a string
through MakeExternal.

We currently use the class name “JSValue” for JSObjects that wrap
primitive values. This name is a common source of confusion. This patch
switches to a name that’s more clear.
In addition to manual tweaks, the patch applies the following mechanical
global replacements:
before | after
--------------------------------|--------------------------------------
if_valueisnotvalue | if_valueisnotwrapper
if_valueisvalue | if_valueiswrapper
js_value | js_primitive_wrapper
JS_VALUE_TYPE | JS_PRIMITIVE_WRAPPER_TYPE
JSPrimitiveWrapperType | JSPrimitiveWrapper type
jsvalue | js_primitive_wrapper
JSValue | JSPrimitiveWrapper
_GENERATED_JSVALUE_FIELDS | _GENERATED_JSPRIMITIVE_WRAPPER_FIELDS
