[clang][driver] Only run multi-arch tests on Darwin This fixes the test introduced in a85670001ba2487988839656299771915ebc7633 that causes failures on non-Darwin systems.

[clang][driver] Fix compilation database dump with multiple architectures Command lines with multiple `-arch` arguments expand into multiple entries in the compilation database. However, the file writes are not appending, meaning subsequent writes end up overwriting the previous ones, resulting in garbled output. This patch fixes that by always appending to the file. rdar://90165004 Reviewed By: dexonsmith Differential Revision: https://reviews.llvm.org/D121997

[clang][driver] Ensure we don't accumulate entries in -MJ files Previously, each job would overwrite the -MJ file. This didn't quite work for Clang invocations with multiple architectures, which got fixed in D121997 by always appending to the -MJ file. That's not correct either, since the file would grow indefinitely on subsequent Clang invocations. This patch ensures the driver always removes the file before jobs fill it in by appending.

// Let's run that again and verify we're not accumulating redundant entries in the same file.
Revert "[Driver][test] Replace ^//$ with empty string" This reverts commit 4817b7729a1846b709ec02b98bfe11b0125f8e8f. It caused some `^/\n` and had some objection about its readability improvement.
