Print tier in DumpJittedMethods. (dotnet/coreclr#27017)

* Print tier in DumpJittedMethods.

I found that useful when reproducing bugs that require `complus_TieredCompilation=1`.

Example:
```
Compiling    0 System.SpanHelpers::IndexOf, IL size = 902, hsh=0xda613814 for Tier-1
Compiling    1 System.Text.Unicode.Utf16Utility::GetPointerToFirstInvalidChar, IL size = 1107, hsh=0xe576e43d
Compiling    2 System.Runtime.Intrinsics.Vector128::CreateScalarUnsafe, IL size = 21, hsh=0x6746a268 for Tier-0
```

* Fix JitFunctionTrace printing.

The opening is using decimal number, but the closing was using hex.

* Add compGetTieringName.
