Add a test-specific tclsh wrapper (`tests/test-tclsh`) that extends the
vendor tclsh wrapper with all `src/` package directories on `TCLLIBPATH`,
allowing the test suite to find in-tree packages without anything
installed at the configured prefix.
Switch all test Makefiles from `$(TCLSH)` to `$(TEST_TCLSH)` so unit and
integration tests use the in-tree interpreter. Replace all references
to `${bindir}/port` and `${bindir}/portindex` with direct invocations of
the in-tree `src/port/port.tcl` and `src/port/portindex.tcl` via the test
tclsh wrapper.
Add `init_tmp_prefix` to all test files that call `mportinit`, creating a
throwaway prefix with `macports.conf`, `sources.conf`, and `share/macports`
data populated from the source tree rather than the installed prefix.
Set `extra_env TCLLIBPATH` in test `macports.conf` files so that
`mportinit`'s environment scrub does not strip `TCLLIBPATH`, which threads
need to resolve packages.
Reorder CI workflows to run `make test` before `make install`, since the
test suite no longer requires an installed prefix.
