Revert of Allow base to depend on allocator (patchset #3 id:60001 of https://codereview.chromium.org/1584893002/ )

Reason for revert:
Made the tree go red - build failure on iOS_Device: https://build.chromium.org/p/chromium.mac/builders/iOS_Device/builds/35574

Original issue's description:
> Allow base to depend on allocator
>
> A smaller, yet key, step to move
>
> From: a situation where mainly executables (but not really) depend on
> allocator, and base needs dependencies (to tcmalloc) to be injected
> from content (which violates the ODR in component buids).
>
> To: a situation where only base depends on allocator and the other
> targets get recursively the required linked flags.
>
> In essence this CL is a more gradual approach to the bigger
> unreviewable crrev.com/1528013002.
>
> How is the transition handled?
> ------------------------------
> After this CL, the situation will be as follows:
> From a build time perspective base will also depend on allocator.
> This will not change anything substantial in static builds and introduce
> yet another (temporary) ODR violation in Linux component builds.
> The big change introduced by this CL is the fact that all the executable
> targets that depend on base (virtualy all) will also get another
> indirect dependency to allocator.
>
> In other words, after this CL executable targets will depend on
> allocator for two reasons:
>  - Because they have an explicit dependency to it (the one I am going to
>    get rid of in the immediate future).
>  - Because this new transitive path I am introducing in base.
>
> Rationale of this approach
> --------------------------
> This allows to restrict the critical changes in a smaller CL easier to
> review, at the cost of the temporary double dependency on base.
> The good things are:
>  - If something will break, this CL will be very easy to revert.
>  - The next cleanups will be straightforward.
>  - We have now smoke tests (crrev.com/1577883002) that will help us
>    realize if something goes wrong.
>
> Next steps
> ----------
> In the next CLs I will:
>  - Remove the content -> base injection layer, and let base directly use
>    the tcmalloc functions it needs.
>  - Remove all the traces of USE_TCMALLOC outside of base.
>  - Start cleaning up the hundreds use_allocator conditionals in the gyp
>    files in a way which is easier to review and produce zero ninja diffs
>    (see crrev.com/1583973002 as an example)
>
> Ninja diffs caused by this change
> ---------------------------------
>  ### Win, static build, GN:   https://paste.ee/p/hvcRp
>  The missing targets (mostly tests) that previously were
>  not depending on allocator, now get that by virtue of the transitive
>  dependency.
>
>  ### Win, static build, GYP:  https://paste.ee/p/AGuKR
>  As above. Just GYP seems to emit the ninja files in a different,
>  inlined, format.
>
>  ### linux static build, GYP:  https://paste.ee/p/kmD7U
>  As above. Plus the new targets also get the -Wl,-u (keep symbol)
>  args as expected by allocator.gyp for the tcmalloc heap profiler.
>
>  ### linux shared build, GYP: https://paste.ee/p/FHHNR
>  Nothing relevant. Just I moved the dependency to allocator from
>  base_unittests to base, and that is the only thing that reflects in the
>  ninja files.
