selftests/resctrl: Rename CQM test as CMT test
CMT (Cache Monitoring Technology) [1] is a H/W feature that reports cache
occupancy of a process. resctrl selftest suite has a unit test to test CMT
for LLC but the test is named as CQM (Cache Quality Monitoring).
Furthermore, the unit test source file is named as cqm_test.c and several
functions, variables, comments, preprocessors and statements widely use
"cqm" as either suffix or prefix. This rampant misusage of CQM for CMT
might confuse someone who is newly looking at resctrl selftests because
this feature is named CMT in the Intel Software Developer's Manual.
Hence, rename all the occurrences (unit test source file name, functions,
variables, comments and preprocessors) of cqm with cmt.
[1] Please see Intel SDM, Volume 3, chapter 17 and section 18 for more
information on CMT: https://software.intel.com/content/www/us/en/develop/articles/intel-sdm.html

selftests/resctrl: Fix incorrect parsing of option "-t"
Resctrl test suite accepts command line argument "-t" to specify the
unit tests to run in the test list (e.g., -t mbm,mba,cmt,cat) as
documented in the help.
When calling strtok() to parse the option, the incorrect delimiters
argument ":\t" is used. As a result, passing "-t mbm,mba,cmt,cat" throws
an invalid option error.
Fix this by using delimiters argument "," instead of ":\t" for parsing
of unit tests list. At the same time, remove the unnecessary "spaces"
between the unit tests in help documentation to prevent confusion.
