[compiler-rt] [compiler-rt][test] Expand and Rewrite Tests for lit Internal Shell Compatibility (PR #106115)

Subject: [PATCH] Expand diff run lines in profiling tests for lit
 compatibility

Expanded the `diff` run lines in several profiling test files to avoid using process substitution (`<(...)`), which is not supported by the `lit` internal shell. The updated commands now explicitly redirect the output of `llvm-profdata show` to temporary files before performing the comparison with `diff`.
