Move wasm-specific members outside of MCSymbolRefExpr::VariantKind (a legacy interface I am eliminating). Most changes are mechanic and similar to what I've done for many ELF targets (e.g. X86 #132149) Notes: * `fixSymbolsInTLSFixups` is replaced with `setTLS` in `WebAssemblyWasmObjectWriter::getRelocType`, similar to what I've done for many ELF targets. * `SymA->setUsedInGOT()` in `recordRelocation` is moved to `getRelocType`. While here, rename "Modifier' to "Specifier": > "Relocation modifier", though concise, suggests adjustments happen during the linker's relocation step rather than the assembler's expression evaluation. I landed on "relocation specifier" as the winner. It's clear, aligns with Arm and IBM’s usage, and fits the assembler's role seamlessly. Pull Request: https://github.com/llvm/llvm-project/pull/133116
