8292177: InitialSecurityProperty JFR event

[gnu-andrew]

This backport introduces the JFR security event, InitialSecurityProperty, and along with it, the caching of the initial security properties which is also used by JDK-8281658 to show the security properties with -XshowSettings.

The change was backported to the Oracle fork of 11u in 11.0.20.

The following changes were necessary for the backport:

• JavaSecurityPropertiesAccess is moved to jdk.internal.misc where SharedSecrets lives in 11u
• ensureClassInitialized in SharedSecrets is called from the unsafe instance in 11u, as with other get*Access() methods in that class
• The patch to module-info.java is not needed as jdk.jfr already has access to jdk.internal.misc in 11u. The 17u addition is to jdk.internal.access.
• There are context differences in JDKEvents.java due to events introduced in later JDK versions.
• The EventNames.java test includes a huge unrelated change to reorganise the order of the variable modifiers. This was applied manually to the names in 11u, which differ slightly from those in 17u.

All jdk.jfr.event tests passed, including the new one, with the exception of TestNative, but that seems to be a setup issue rather than a regression caused by this patch (Error. Use -nativepath to specify the location of native code)

Not sure why the Mac port won't build (no error message), but I can't see a Java-only change causing this.

Ok, seems the Mac OS 11 runner image was removed on the 28th of June. We need to backport JDK-8318039

/approval request This is part of a number of improvements to the visibility of security property settings and is followed by JDK-8281658 which allows them to be output from the command line. While I realise it is an enhancement being backported late in the 11u lifecycle, easy access to these security properties is often invaluable when debugging various issues. The same backport was already made to 17 during its maintenance period (17.0.7) and Oracle support this in their 11u fork from 11.0.20. Patch did not backport cleanly, but was reviewed by Paul Hohensee.
