Test runs log some of their output to files inside the LLDB session dir. This
session dir is shared between all tests, so all the tests have to make sure they
choose a unique file name inside that directory. We currently choose by default
`<test-class-name>-<test-method-name>` as the log file name. However, that means
that if not every test class in the test suite has a unique class name, then we
end up with a race condition as two tests will try to write to the same log
file.
I already tried in D83767 changing the format to use the test file basename
instead (which we already require to be unique for some other functionality),
but it seems the code for getting the basename didn't work on Windows.
This patch instead just changes that dotest stores the log files in the build
directory for the current test. We know that directory is unique for this test,
so no need to generate some unique file name now. Also removes all the
environment vars and parameters related to the now unused session dir.
The new log paths now look like this for a failure in 'TestCppOperators`:
```
./lldb-test-build.noindex/lang/cpp/operators/TestCppOperators.test_dwarf/Failure.log
./lldb-test-build.noindex/lang/cpp/operators/TestCppOperators.test_dsym/Failure.log
./lldb-test-build.noindex/lang/cpp/operators/TestCppOperators.test_gmodules/Failure.log
```

in two lldb_log files.

different configuration-based files using the config file. For example:

sys.stdout = open("/tmp/lldbtest-stdout", "w")
compilers = ["gcc", "llvm-gcc"]
archs = ["x86_64", "i386"]
split_stderr = True # This will split the stderr into configuration-specific file
split_stdout = True # This will split the stdout into configuration-specific file
will produce:
/tmp/lldbtest-stderr

/tmp/lldbtest-stderr.arch=i386-compiler=llvm-gcc
/tmp/lldbtest-stderr.arch=x86_64-compiler=gcc

as a result of splitting stderr and stdout. In addition, each configuration can have
its individual top level relocated directory to house the test files as well as the
intermediate files by using '-r dir' to relocate the tests into a new relocated directory
instead of running the tests in place.

order to customize the running of the test suite. For the time being, the
supported customizations are:
o redirecting stdout and/or stderr
o specifying a list of compilers to build the test programs
o specifying a list of architectures to build the test programs for
Also checked into the examples/test directory some example files which
demonstrate the usage for the above customizations.
