This reverts commit 13a04aba.

Reason for revert: Breaks v8 roll (https://chromium-review.googlesource.com/c/chromium/src/+/1698024)

Original change's description:
> fix: move V8_EXPORT_PRIVATE marks to prevent unresolvable references
> 
> This change fixes missing symbol errors in the Windows 10 on ARM build
> of Node.js.
> 
> When a whole class is marked for export, all of its members are marked
> as well. This can be a problem when inline members call undefined yet
> inline members of other classes: the exported function will contain a
> reference to the undefined inline function that should be satisfied at
> link time, but because the other function is inline no symbol will be
> produced that will satisfy that reference.
> 
> Clang gets around this by masking inlined class members from export
> using /Fc:dllexportInlines-. This is why b0a2a567 worked.
> 
> Node.js' Windows builds use MSVC and so do not have access to this
> flag. This results in unresolved symbols at link time.
> 
> Bug: v8:9465
