Subject: [PATCH] v8: fix -Wtemplate-body error with GCC 15 on ia32

GCC 15 introduced -Wtemplate-body (enabled by default as an error) which
performs stricter name lookup checking inside template bodies. In the
Int64LoweringReducer template class (only compiled for 32-bit targets),
the expression `__ Tuple<Word32, Word32>(...)` is ambiguous in a
dependent context because GCC cannot determine whether `Tuple` after
the `__` macro expansion (`Asm().`) refers to a template member function
or the struct type `Tuple`.

Add the C++ `template` disambiguator keyword to tell the compiler that
`Tuple` is a dependent template name. This is the standards-correct fix
and is backward-compatible with older GCC versions.

This is a minimal backport of the fix already present in upstream V8
(main branch), where the method was additionally renamed from `Tuple` to
`MakeTuple`.

Upstream-Status: Backport [https://github.com/nodejs/node/commit/7772a2df9d0b4db9947dbb902b4aec33c35401c0]
