Add needs-symlink directive to compiletest
This is an alternative to #126846 that allows running symlink tests on Windows in CI but will ignore them locally if symlinks aren't available. A future improvement would be to check that the `needs-symlink` directive is used in rmake files that call `create_symlink` but this is just a quick PR to unblock Windows users who want to run tests locally without enabling symlinks.

all of these currently force stronger frame pointers, and
currently the CLI does not override the target

Don't build a broken/untested profiler runtime on mingw targets
Context: https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Why.20build.20a.20broken.2Funtested.20profiler.20runtime.20on.20mingw.3F
#75872 added `--enable-profiler` to the `x86_64-mingw` job (to cause some additional tests to run), but had to also add `//@ ignore-windows-gnu` to all of the tests that rely on the profiler runtime actually *working*, because it's broken on that target.
We can achieve a similar outcome by going through all the `//@ needs-profiler-support` tests that don't actually need to produce/run a binary, and making them use `-Zno-profiler-runtime` instead, so that they can run even in configurations that don't have the profiler runtime available. Then we can remove `--enable-profiler` from `x86_64-mingw`, and still get the same amount of testing.
This PR also removes `--enable-profiler` from the mingw dist builds, since it is broken/untested on that target. Those builds have had that flag for a very long time.

The profiler runtime is no longer built in mingw test jobs, so these tests
should naturally be skipped by `//@ needs-profiler-support`.

compiletest: Stricter parsing of `//@ normalize-*` headers
I noticed some problems with the existing parser for these headers:
- It is extremely lax, and basically ignores everything other than the text between two pairs of double-quote characters.
- Unlike other name-value headers, it doesn't even check for a colon after the header name, so the test suite contains a mixture of with-colon and without-colon normalization rules.
- If parsing fails, the header is silently ignored.
The latter is especially bad for platform-specific normalization rules, because the lack of normalization probably won't be noticed until the test mysteriously fails in one of the full CI jobs.

run-make: annotate library with `#[must_use]` and enforce `unused_must_use` in rmake.rs
This PR adds `#[must_use]` annotations to functions of the `run_make_support` library where it makes sense, and adjusts compiletest to compile rmake.rs with `-Dunused_must_use`.
The rationale is that it's highly likely that unused `#[must_use]` values in rmake.rs test files are bugs. For example, unused fs/io results are often load-bearing to the correctness of the test and often unchecked fs/io results allow the test to silently pass where it would've failed if the result was checked.
This PR is best reviewed commit-by-commit.

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 https://github.com/ferrocene/ferrocene/blob/383cbc80f4e85859a4055f121f15dac329908346/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.

This header is much more restrictive than its old name would suggest. As a
result, most of the tests that use it don't actually run in any CI jobs.

Change how runmake v2 tests are executed
This PR makes execution of v2 runmake tests more sane, by executing each test in a temporary directory by default, rather than running it inside `tests/run-make`. This will have.. a lot of conflicts.
Fixes: https://github.com/rust-lang/rust/issues/126080
Closes https://github.com/rust-lang/rust/issues/125726, because it removes `tmp_dir`, lol.

Port `tests/run-make-fulldeps/hotplug_codegen_backend` to ui-fulldeps
This is the last remaining run-make-fulldeps test, which means I actually had to leave behind a dummy README file to prevent compiletest from complaining about a missing directory.
(Removing the run-make-fulldeps suite entirely is non-trivial, so I intend to do so in a separate PR after this one.)
---
I wasn't sure about adding a new kind of aux build just for this one test, so I also tried to just port this test from Makefile to [rmake](https://github.com/rust-lang/rust/issues/121876) instead.
But I found that I couldn't get rmake to fully work for a run-make-fulldeps test, which convinced me that getting rid of run-make-fulldeps is worthwhile.

And also remove some environment variables passed to compilation of `rmake.rs`.

compiletest: Allow multiple `//@ run-flags:` headers
While working on some tests, I was annoyed to find that multiple `// `@run-flags:`` headers do not combine with each other (as `//@ compile-flags:` headers do), and instead all but one are silently discarded.
This makes it impossible to split long flag lists into multiple lines.
Fortunately it's easy to just recycle the existing logic from the other command-line-flags headers.
