[OE-core] [PATCH v2 11/12] oeqa/selftest/gcc: Create selftest case for gcc test suite

[Nathan Rossi]

Create a oeqa selftest test case to execute the gcc test suites and
report the results. The results are populated into the extraresults
variable of the test case which are written to testresults.json for
resulttool to analyse.

An additional subclass is created to separate the execution with qemu
linux-user and qemu system. The GccSelfTestSystemEmulated test case
handles setup of the target image as well as execution with runqemu.

Changed in v2:
- Change to using only gcc-runtime recipe and associated check targets
- Remove gxx/g++ testcase, this is part of the "check-gcc" target
- Populate test results as ptestresults
- Rename BUILD_TEST_* to TOOLCHAIN_TEST_*
- Mark tests with 'machine' tag
