wpewebkit: port custom Digi patches to 2.46.X

Out of the three patches we currently apply to v2.44.4, two are no longer
needed for v2.46.7:

    * 0001-Build-fix-when-LAYER_BASED_SVG_ENGINE-is-off.patch is already
      included in v2.46.X releases
    * 0001-DMABufVideoSinkGStreamer-disable-sink-unconditionall.patch is no
      longer needed, since the GL sink is chosen by default in v2.46.7

Only port 0001-UIProcess-WebProcessPool-always-swap-process-when-us.patch to
avoid performance issues on platforms with memory restrictions.

Keep the v2.44.4 patches in case customers want to use said version, and
clearly separate the patchsets for both versions.

+Subject: [PATCH] UIProcess: WebProcessPool: always swap process when using
+ non-HTTP(S) protocols
+
+When browsing through a local web application via the file:// protocol, the
+same WPEWebProcess is re-used for all pages. Browsing through several memory
+intensive pages in a row (especially multimedia) causes the web process to hog
+lots of memory, which can cause issues on systems with small RAM sizes. For
+example, on ConnectCore platforms with 1 GiB of RAM, opening a WebGL sample
+followed by playing a video sometimes causes a kernel panic due to extremely
+low CMA memory, which is needed for the video decoding process.
+
+To avoid this, make sure a new WPEWebProcess is generated each time a page is
+opened on non-HTTP(S) protocols such as file://. This adds some loading time
+overhead, but it assures that each page's memory is freed when exiting it,
+drastically reducing the chances of unexpected behavior. To accomplish this:
+
+    * Set m_processSwapsOnNavigationWithinSameNonHTTPFamilyProtocol to "true"
+      to ensure the web process isn't re-used when navigating with a
+      non-HTTP(S) protocol. The WPE version of WebKit doesn't expose the API
+      that can change this value at runtime, so simply change the default value
+    * Skip the same-site navigation check when non-HTTP(S) process swap is
+      enabled and the protocol is non-HTTP(S). Otherwise, the same web process
+      will get re-used even if non-HTTP(S) process swap is enabled.
