RFR(S) : 8181391: remove explicit @build actions for the top level testlibary classes

[Alan Bateman]

The library tests have been running in agentvm mode and with concurrency 
for several years and the intermittent CNFE/NCDFE issues have always 
been worked around by avoiding implicit compilation.  There seems to be 
several more intermittent failures in jdk10/jdk10 compared to jdk9/dev 
with tests that have been changed to revert to implicit compilation. So 
I agree with Martin that Jon Gibbons (with his jtreg hat on) is the 
right person to comment on this. If the issue is really 
CODETOOLS-7901986 (and Ioi's analysis looks good) then I think we need 
to get that into a jtreg build before changing lots of tests to not 
explicitly compile the test infrastructure that they use.
