RFR: 8273315: Parallelize and increase timeouts for java/foreign/TestMatrix.java test

[Aleksey Shipilev]

This test runs a lot of configurations, and spends a lot of time serially. This is especially pronounced when run in prospective tier4 runs (JDK-8273314). There are reports of multi-hour runs (see JDK-8271613). We can parallelize the test configurations for this test to make it hurt less. Also, timeouts need to be increased for `TestUpcall` test configs, because some of them are very slow in fastdebug mode. 

Sample run:


$ time CONF=linux-x86_64-server-fastdebug make run-test TEST=java/foreign/TestMatrix.java | ts -s
00:00:00 Building target 'run-test' in configuration 'linux-x86_64-server-fastdebug'
00:00:03 Test selection 'java/foreign/TestMatrix.java', will run:
00:00:03 * jtreg:test/jdk/java/foreign/TestMatrix.java
00:00:03

If we don't parallelize, then those 130 minutes are spent serially.
