Slice 2 (Phase 1a) of the M9 Monterey retarget. Converts all pure Core
suites (argv builders, CGATS/CUPS/profcheck/gamut-mesh parsers, colour
math, file/artefact helpers, classifiers) to XCTestCase, and adds the
shared assertAsyncThrows helper for the async-throws sites that Slice 3
will convert.
Deferred to Slice 3 (kept on Swift Testing in mixed files):
ProcessManagerTests, ArgyllRunner*Tests, ProcessRunSupportTests,
store/UI suites, and the runner suites embedded in TargenTests /
PrinttargTests / ProcessManagerTests.
Also qualifies six bare `throw .case` expressions in CGATSParser with
CGATSParseError — they only compiled under typed throws, which Slice 1
demoted to untyped `throws`; without this the ICCeryCore target fails to
build and no test gate can run.
