RFR: 8346233: [mobile] enable static-libs-image for iOS

[Johan Vos]

This PR makes it possible to build hotspot with zero interpreter for ios using
`make static-libs-image`

This creates, amongst the native classlibs that we already had, a libjvm.a library that can be used on iOS.

Configuring the build can be done similar to what I do in my configuration:

sh configure \
--with-conf-name=zero-ios-aarch64 \
--disable-warnings-as-errors \
--openjdk-target=aarch64-macos-ios \
--with-build-jdk=/opt/jdk-25-jv.jdk \
--with-boot-jdk=/opt/jdk-24.jdk/Contents/Home \
--with-jvm-variants=zero \
--with-libffi-include=/Users/johan/libffi/exp/t2/libffi-3.4.5/build_iphoneos-arm64/include \
--with-libffi-lib=/Users/johan/libffi/exp/t2/libffi-3.4.5/build_iphoneos-arm64/.libs \
--with-sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk \
--with-cups-include=../support/cups-2.3.6
