run-make: audit tests that codegen for specific targets

[jieyouxu]

Tests doing codegen for specific targets need //@ needs-llvm-components directives.
These are the tests that are currently missing the directives and failing if LLVM is built without various aarch64/arm/thumb components or wasm.

• tests\run-make\print-target-list
• tests\run-make\print-to-output
• tests\run-make\print-cfg
• tests\run-make\target-without-atomic-cas

E.g. for print-target-list this looks a bit awkward, maybe we can dump //@ needs-llvm-components: $KNOWN_LLVM_COMPONENTS, where $KNOWN_LLVM_COMPONENTS is shamelessly stolen from tidy:

rust/src/tools/tidy/src/target_specific_tests.rs

Lines 13 to 31 in 0f6e1ae

	const KNOWN_LLVM_COMPONENTS: &[&str] = &[
	"aarch64",
	"arm",
	"avr",
	"bpf",
	"csky",
	"hexagon",
	"loongarch",
	"m68k",
	"mips",
	"msp430",
	"nvptx",
	"powerpc",
	"riscv",
	"sparc",
	"systemz",
	"webassembly",
	"x86",
	];

Between this directive and COMPILETEST_REQUIRE_ALL_LLVM_COMPONENTS, it is not exactly very clear what's happening.
