Mini dumps are not supported on WASM - the createdump binary doesn't exist and the browser environment doesn't support crash dumps. Setting DOTNET_DbgEnableMiniDump=1 was causing runtime init to fail because PROCAbortInitialize depends on g_szCoreCLRPath which is never set on WASM (LOADInitializeCoreCLRModule is already skipped). Fixes dotnet#124088

Pull request overview
This PR prevents CoreCLR runtime initialization from failing on WebAssembly when DOTNET_DbgEnableMiniDump=1 is set, by skipping PROCAbortInitialize() on TARGET_WASM where minidumps/createdump aren’t supported and g_szCoreCLRPath is not initialized.
Changes:
- Wrap the
PROCAbortInitialize()call inPAL_InitializeCoreCLRwith#ifndef TARGET_WASMto avoid failing startup on WASM.
