  Remove iOS 5 check for tailcalls on ARM (#133354)

Fixes #102053

The check was added in 8decdc472f308b13d7fb7fd50c3919db086c0417, and at
the time iOS 5 was the latest iOS version, before that commit tail calls
were disabled for all ARMv7 targets. Testing a build of wasm3 with the
patch on a device running iOS 3.0 shows a noticeable performance
improvement and no issues.
