8260518: Change default -mmacosx-version-min to 10.12

[VladimirKempik]

Please review this backport of JDK-8260518 to jdk11u-dev
The backport is not applying clean due to the context code difference.
It's needed mostly to resolve this compilation error on macos-aarch64
splashscreen_sys.m:274:39: error: 'NSAlphaFirstBitmapFormat' is deprecated: first deprecated in macOS 10.14 [-Werror,-Wdeprecated-declarations]
This will allow to add macos-aarch64 build into github actions for jdk11u-dev ( once jep-391 backport is integrated)

Lgtm.

Note to Maintainers: 10.9 through 10.14 are eol, and the oldest machines supported by 10.12 are from 2009/2010, see https://support.apple.com/kb/SP742?locale=en_USh. Imo it's safe to say that it's very unlikely there are machines running OSX versions earlier than 10.12.

While I agree, why take the risk? This can be easily set conditionally for aarch64.

While I agree, why take the risk? This can be easily set conditionally for aarch64.

This was reasoned in the bug description:

Having a large gap between the target versions becomes problematic as we hit a lot of deprecation warnings in shared code. To be able to fix these deprecation warnings, we need a smaller version gap.

[VladimirKempik]

@GoeLin, two weeks later - no objections ( https://mail.openjdk.java.net/pipermail/jdk-updates-dev/2022-February/012026.html )
can we get approval or as an alternative, I can reduce this fix and not change min macos version for intel64.
I would like to make macos-aarch64 port buildable without --disable-warnings-as-errors before rdp2.

Can this be merged?

[phohensee]

The JBS issue has been tagged with jdk11u-fix-yes, so yes, it can be merged.
