Mono WASM PInvoke Table generation does not handle backticks

[barbieri-quisitive]

Description

Microsoft.CognitiveServices.Speech puts the following line into the pinvoke-table.h:

void wasm_native_to_interp_Microsoft_CognitiveServices_Speech_csharp_InteropEvent`1_FromNativeCallback (int arg0,int arg1,int arg2) {

The backtick (`) after InteropEvent is not recognized by the C compiler.

I found the following recent resolved bug in which a character needed to be escaped, it sounds like more escaping just needs to be done: #93999

Reproduction Steps

Build a WASM project that includes Microsoft.CognitiveServices.Speech 1.35.0 as a dependency.

Expected behavior

Successful build

Actual behavior

Tried to reproduce this locally but it doesn't fail. Looks like the issue has been solved in .Net 9.
In pinvoke_table.h I don't see backtick after InteropEvent but 60
