libcamera: update to 0.4.0

Upgrade libcamera to version 0.4.0, gaining support for ARM Mali-C55 ISP.

Patches 0002-options-Replace-use-of-VLAs-in-C.patch and
0001-rpi-Use-malloc-instead-of-variable-length-arrays.patch are obsolete.
Issues have been fixed upstream (differently).

-Subject: [PATCH] options: Replace use of VLAs in C++
-
-Clang++ 18 is fussy about this with new warning checks.
-
-   ../git/src/apps/common/options.cpp:882:20: error: variable length arrays in C++ are a Clang extension [-Werror,-Wvla-cxx-extension]
-      882 |         char shortOptions[optionsMap_.size() * 3 + 2];
-          |                           ^~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Therefore replace using VLAs with alloca and malloc/free
