RFR 8198697: Simplify platform encoding initialization tweak

In an effort to untangle some of the issues with property initialization
I was looking
at the platform encoding initialization and found a simplification.
Currently, the initialization occurs as a side effect of the first call
to JNU_NewStringPlatform and
involves a upcall to get sun.jnu.encoding from the system properties.
The value is cached for later use.
The native System.initProperties determines the platform specific
encoding via java_props_md.c and does an upcall to set the
sun.jnu.encoding system property, taking care to do it before the first
string that needs platform encoding.
The change directly initializes the platform encoding fast path before
it is needed to encode platform strings.
And moves the setting sun.jnu.encoding system property after the command
line arguments are inserted
keeping it from being overridden by -D on the command line that can only
with code that later reads the property.
Please review and comment.
