[clang][test][NFC] Also test for serialization in AST dump tests, part 1/n. The outputs between the direct ast-dump test and the ast-dump test after deserialization should match modulo a few differences. For hand-written tests, strip the "<undeserialized declarations>"s and the "imported"s with sed. For tests generated with "make-ast-dump-check.sh", regenerate the output. Part 1/n.

// Test without serialization:
// RUN: %clang_cc1 -triple wasm32-unknown-unknown -ast-dump %s \
// RUN: | FileCheck --strict-whitespace %s
[WebAssembly] Improve clang diagnostics for wasm attributes This patch addresses the review comments on r352930: - Removes redundant diagnostic checking code - Removes errnoneous use of diag::err_alias_is_definition, which turned out to be ineffective anyway since functions can be defined later in the translation unit and avoid detection. - Adds a test for various invalid cases for import_name and import_module. This reapplies D59520, with the addition of adding `InGroup<IgnoredAttributes>` to the new warnings, to fix the Misc/warning-flags.c failure. Differential Revision: https://reviews.llvm.org/D59520
