x check checks rust-analyzer by default

[Noratrieb]

Sometimes when changing compiler internals, I run x check to make sure I didn't break tools and codegen backends. This also checks rust-analyzer by default, which is not very useful, I cannot break that.

If we want to keep that, it would at least be useful to put it last so I can Ctrl-C out of it. Currently, rustfmt is checked after rust-analyzer.

mentoring instructions: switch the order of these two lines:

rust/src/bootstrap/builder.rs

Lines 706 to 707 in dc25fbe

	check::RustAnalyzer,
	check::Rustfmt,

@Nilstrieb points out that Cargo also isn't checked by default, so for consistency it would be nice for RustAnalyzer not to be either:

rust/src/bootstrap/check.rs

Line 350 in dc25fbe

const DEFAULT: bool = true;
