cranelift: Allow call and call_indirect in runtests (#4667)

Browse Source 
* cranelift: Change test runner order

Changes the ordering of runtests to run per target and then per function.

This change doesn't do a lot by itself, but helps future refactorings of runtests.

* cranelift: Rename SingleFunctionCompiler to TestCaseCompiler

* cranelift: Skip runtests per target instead of per run

* cranelift: Deduplicate test names

With the upcoming changes to the runtest infrastructure we require unique ExtNames for all tests.

Note that for test names we have a 16 character limit on test names, and must be unique within those 16 characters.

* cranelift: Add TestFileCompiler to runtests

TestFileCompiler allows us to compile the entire file once, and then call the trampolines for each test.

The previous code was compiling the function for each invocation of a test.

* cranelift: Deduplicate ExtName for avg_round tests

* cranelift: Rename functions as they are defined.

The JIT internally only deals with User functions, and cannot link test name funcs.

This also caches trampolines by signature.

* cranelift: Preserve original name when reporting errors.

* cranelift: Rename aarch64 test functions

* cranelift: Add `call` and `call_indirect` tests!

* cranelift: Add pauth runtests for aarch64

* cranelift: Rename duplicate s390x tests

* cranelift: Delete `i128_bricmp_of` function from i128-bricmp

It looks like we forgot to delete it when it was moved to
`i128-bricmp-overflow`, and since it didn't have a run invocation
it was never compiled.

However, s390x does not support this, and panics when lowering.

* cranelift: Add `colocated` call tests

* cranelift: Rename *more* `s390x` tests

* cranelift: Add pauth + sign_return_address call tests

* cranelift: Undeduplicate test names

With the latest main changes we now support *unlimited* length test names.

* cranelift: Add LibCall tests

* cranelift: Revert more test names

These weren't auto reverted by the previous revert.

* cranelift: Disable libcall tests for aarch64

* cranelift: Runtest fibonacci tests

* cranelift: Misc cleanup
