Remove APPLE_ARMV7S-specific code from Blink.

Remove APPLE_ARMV7S-specific code from Blink.

Blink includes some code that is specific to the ARMv7s architecture,
intended for Apple devices, that predates the fork from WebKit. Blink is
not built for iOS devices and this code path is not tested.

This patch removes all references to the "CPU(APPLE_ARMV7S)" macro
(and equivalent "WTF_CPU_APPLE_ARMV7S") from the code, along with all
code gated by this macro. It does not, however, remove other references
to "defined(__ARM_ARCH_7S__)".
