OvmfPkg/Tcg2ConfigPei: trivial coding style updates
- the @file comment block should match between INF and main C file - rewrap / refill columns to 79 characters - insert space before opening paren - prefix and suffix //-style comment block with empty // lines - fix indentation of arguments in multi-line function call - general tab spacing (indent step) is 2 in edk2, unlike QEMU's 4 No functional changes.
