newlib: add 4.3.0.20230120

Add the 4.3.0.20230120 and update the required patches. As of this
release the newlib-global-atexit is mandatory so set this to default y.
Included is an upstream patch to support older GCC versions.

+Subject: [PATCH] libc: arm: Implement setjmp GCC backwards compatibility.
+
+When compiling Newlib for arm targets with GCC 12.1 onward, the
+passing of architecture extension information to the assembler is
+automatic, making the use of .fpu and .arch_extension directives
+in assembly files redundant.
+
+With older versions of GCC, however, these directives must be
+hard-coded into the `arm/setjmp.S' file to allow the assembly of
+instructions concerning the storage and subsequent reloading of the
+floating point registers to/from the jump buffer, respectively.
+
+This patch conditionally adds the `.fpu vfpxd' and `.arch_extension
+mve' directives based on compile-time preprocessor macros concerning
+GCC version and target architectural features, such that both the
+assembly and linking of setjmp.S succeeds for older versions of
+Newlib.
