Duo Wang 9a325cfe98 [test][Backtracing] Mark SWIFT_BACKTRACE=preset=friendly tests UNSUPPORTED under remote-run (#90512) ...

The `FRIENDLY` presentation of the backtracer reads the referenced
source file at its compile-time absolute path so it can print
surrounding lines. DWARF bakes in that absolute path at build time.

Under remote-run the source tree isn't mirrored on the remote (and DWARF
paths aren't remapped), so the friendly formatter has no file to read
and only frame headers come out — the tests' FRIENDLY-prefix CHECK lines
never match.

Making this work end-to-end would need either a source-tree upload
scoped to each test or `-file-prefix-map` at compile time; both are
non-trivial work. Mark them `UNSUPPORTED: remote_run` for now.
