Rollup merge of #126256 - ferrocene:lw-target-subst, r=albertlarsan68

Add {{target}} substitution to compiletest

In ferrocene we have ui tests testing the cli interface of the compiler, one of which tests the `--target` flag. To be able to run this on all targets we require a way to specify a valid target in the `compile-flags` directive that is target independent, as otherwise we can only run the test against the one target we choose to supply in the flags. See 383cbc80f4/tests/ui/ferrocene/compiler-arguments/target/target.rs

We figured the project might be able to make use of this substitution as well in the future.
