build.d: Add test target to run the test suite

[MoonlightSentinel]

Calling ./build.d test will now build dmd and run the test suite as done for the makefile.

From a quick look, this PR seems to be the cause of the Azure pipeline failures.
While the CI was green, after the merge, the following error appears:

Error: 'unittest' not found
##[error]Cmd.exe exited with code '3'.

The failure happens while building druntime. Looking at druntime's commit history, there's nothing that could have triggered this. So the issue either comes from this PR, or a configuration change on the Azure side.

[MoonlightSentinel]

From a quick look, this PR seems to be the cause of the Azure pipeline failures.
While the CI was green, after the merge, the following error appears:

The CI doesn't use the test target from build.d, so this PR is not to blame.

The failure happens while building druntime. Looking at druntime's commit history, there's nothing that could have triggered this. So the issue either comes from this PR, or a configuration change on the Azure side.

Note that Azure uses the configuration files found in .azure-pipelines from this repo.

[Geod24]

Yeah, I'm also puzzled because the diff does not seem like it could cause this.

But take a look at the pipeline:

Iain's merge (#11827) failed for a different reason (in the test-suite). The merge commit for this PR is the first to show the recurrent issue with Windows_LDC_MinGW win32-ldc.

There's a simple way to test this though. I'll submit a revert PR.
