ATHARVA d98784b972 Fix crash when initializing class with omitted base class (#7740 )

### Description
When looking up default initializers for class elements in
`ConvertStructToClass`, the compiler previously assumed that every
member looked up from the class scope was a `FieldDecl` and called
`GetAs<SemIR::FieldDecl>` directly.

For a derived class with a base class, looking up `base` returns a
`BaseDecl`, which caused a `CHECK` assertion failure when casting to
`FieldDecl`. Use `TryGetAs<SemIR::FieldDecl>` instead so non-`FieldDecl`
entries like `BaseDecl` are recognized as having no default initializer,
cleanly diagnosing that the `base` field is missing.

Fixes #7722
