qt5script: fix build issue with 32-bits armv8-a

Adds WTF platform support for the 32-bits armv8-a architectures.

Fixes:

	In file included from ../3rdparty/javascriptcore/JavaScriptCore/config.h:26,
	                from ../3rdparty/javascriptcore/JavaScriptCore/pcre/pcre_compile.cpp:44:
	../3rdparty/javascriptcore/JavaScriptCore/wtf/Platform.h:370:6: error: #error "Not supported ARM architecture"
	#    error "Not supported ARM architecture"
	     ^~~~~

The patch is based on two upstream fixes in WebKit[1][2].

+Subject: [PATCH] Detect 32-bits armv8-a architecture
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+These toolchains define __ARM_ARCH_8A__ (for ARM architecture version)
+and __arm__ (for 32-bits word-size; __aarch64__ for 64-bits).
+
+This commit catches this new architecture (armv8a) within a #ifdef/#endif
+inside the if statement dedicated for 32-bits ARM detection. See commit
+from WebKit [1] and [2].
