    deps: V8: cherry-pick 37baecdd9479

    Original commit message:

        [base] Guard int8_t ReadUnalignedValue overload on Solaris

        On Solaris, int8_t is a typedef for char, so this overload collides with
        ReadUnalignedValue(const char*) and fails to compile. Guard it with
        V8_OS_SOLARIS, as already used elsewhere in the platform code.

        Introduced in:
