Avoid `strlen()` for `ClassLinker::FindClass()`...

... and related functions in most cases.

Note that the `CompilerDriver` previously resolved the
`ClassLoader` and `TransactionAbortError` using the provided
class loaders. We're now using the `ClassLoader` from the
class roots and resolving the `TransactionAbortError` in the
BCP class loader.
