Fix build on 32-bit

Reviewed by Yusuke Suzuki and Justin Michaud.

I attempted to build WebKitGTK on Debian 12 32-bit using only system
libraries ('--no-experimetal-features').  Exactly the same build
procedure as the WebKitGTK Debian 12 64-bit bot, but on 32-bit.

I got a couple of build errors, which this commit fixes.

This does not look right. Do we need to include bmalloc headers?

[dpino]

Right, 'bmalloc.h' was not adtually needed.

[justinmichaud]

I think this means that we should include wtf/TZoneMalloc instead

[Constellation]

Why isn't it wtf/TZoneMalloc.h? Also, SYSTEM_MALLOC guard is not necessary

[dpino]

Header wtf/TZoneMalloc.h is already included in the file. It doesn't seem header <bmalloc/TZoneHeap.h> is necessary as it's already included via wtf/TZoneMalloc.h, so I removed it.

[dpino]

FWIW, the inclusion of header bmalloc/TZoneHeap.h was causing a build error in WebKitGTK 32-bit (Debian 12):

/home/buildbot/worker/webkit/WebKitBuild/GTK/Release/WebCore/PrivateHeaders/WebCore/EventTarget.h:50:10: fatal error: bmalloc/TZoneHeap.h: No such file or directory
   50 | #include <bmalloc/TZoneHeap.h>
	  |          ^~~~~~~~~~~~~~~~~~~~~

To fix this build error I followed the same pattern as other files that also include <bmalloc/TZoneHeap.h>, such as https://github.com/WebKit/WebKit/blob/main/Source/WebKit/Platform/IPC/Connection.h#L87 and https://github.com/WebKit/WebKit/blob/main/Source/WebKit/Platform/IPC/Decoder.h#L48.

Please include wtf headers

Please include wtf headers

Sorry, I don't understand this comment. The changes applied are enough to make WebKitGTK build on Debian 12 32-bit.

[Constellation]

See Justin's comment. Including bmalloc header is not correct
