LOG: [clang] NFC: Deprecate `FileEntry::getName()` (#68157)

All uses of `FileEntry::getName()` were removed in favor of
`FileEntryRef::getName()`. This patch finally formally deprecates that
function. The plan is to remove it entirely in the main branch after we
cut the release branch for LLVM 18.

Modified: 
    clang/include/clang/Basic/FileEntry.h
    clang/unittests/Basic/FileManagerTest.cpp
    llvm/include/llvm/Support/Compiler.h

Removed:
