Mark Mentovai 1669ca2bac test: Rework TestPaths interface for obtaining 32-bit build artifacts
The design for running all Crashpad unit tests on Chromium’s try- and
buildbots involves pulling all tests into a single monolithic
crashpad_tests executable. Many Crashpad tests base the name of their
child executables or modules on the name of the main test executable.
Since the main test executable will have a different name in the
in-Chromium build, knowledge of the test executable name (referred to as
“module” here) needs to be added to the tests themselves.

This introduces TestPaths::BuildArtifact(), which allows the module name
to be specified. For Crashpad’s standalone build, the module name is
verified against the main test executable’s name.
TestPaths::BuildArtifact() can also locate paths in the alternate 32-bit
output directory for 64-bit Windows tests, taking on the responsibility
for what the new (5e9ed4cb9f69) TestPaths::Output32BitDirectory(), now
obsolete, did.
