RFR (S) 8202339: [TESTBUG] Consolidate the tests in runtime/SharedArchiveFile and runtime/appcds

[coleen.phillimore at oracle.com]

Summary: moved appcds and SharedArchive files to test/hotspot/runtime/cds

This is 99% tedious.  I moved the files with hg move and fixed the 
directory references in the tests to 'cds'.   Tested with mach5 
hs-tier1,2,3.
