Özgür 29018f38a6 Fix name mangling of generic impls (#6533 )

### Description
Mangling collisions occur when implementing interfaces with generic
parameters. The mangler does not use the specific id, causing the same
symbol `_C[FunctionName].[PackageName]:[InterfaceName].[PackageName]` to
be generated for all of the implementations below:
```carbon
// Generic interface parameters ignored
impl C as I(A)
impl C as I(B)

// Generic class parameters ignored
impl D(A) as I
impl D(B) as I

// Both ignored
impl D(A) as I(A)
impl D(B) as I(B)
```

### Changes
Updated the mangling logic for `SemIR::ClassDecl` and
`SemIR::InterfaceDecl` to include the specific id. Now the mangling
ensures unique symbols for generic implementations using the format:

`_C[FunctionName].[FunctionSpecificId].[PackageName]:[InterfaceName].[InterfaceSpecificId].[PackageName]`.

Closes #6498
