Poorly performing hash used in the DBI/EE

[hoyosjs]

Update: Exception.ToString() also hits this code path and so we are leaving it in .NET 9 for futher investigation

There are a few places in the DBI that rely on CordbSafeHashTable/CHashTableAndData such as

• CordbHashTableEnum
• CordbProcess
• CordbClass
• CordbAppDomain
• CordbModule
• CordbFunction

The backing hash table, CHashTable, doesn't grow as items keep getting added. This results in a steep performance degradation as the collections grow larger. Common reports include difficulty loading dumps containing thousands of modules. A possible solution would be to replace CHashTable with an SHash.

Internal Microsoft team reported that they see a contention around access to DebuggerMethodInfoTable hashtable in a process that throws a lot of exceptions:

DebuggerMethodInfoTable is implemented as CHashTableAndData.
