  [ProfileData] Remove clear() from SampleProfileFuncOffsetTable (NFC) (#209301)

This patch deletes the default constructor of
SampleProfileFuncOffsetTable and removes its clear() method.

SampleProfileFuncOffsetTable is designed to lock its operational mode
(in-memory or on-disk) strictly at construction time and remain valid
throughout its lifetime. By deleting the default constructor and
removing clear(), we ensure that an instance never enters an
uninitialized or cleared state while kept alive.

When SampleProfileReader needs to discard or reload the table, it
resets and replaces the wrapping std::optional directly instead of
clearing the table in-place.
