[SHT_LLVM_BB_ADDR_MAP] Add an option to skip emitting bb entries (#114447 )

Sometimes we want to use a `PgoAnalysisMap` feature that doesn't require
the BB entries info, e.g. only the `FuncEntryCount`, but the BB entries
is emitted by default, so I'm adding an option to skip the info for this
case to save the binary size(can save ~90% size of the section). For
implementation, it extends a new field(`OmitBBEntries`) in
`BBAddrMap::Features` for this and it's controlled by a switch
`--basic-block-address-map-skip-bb-entries`.

Note that this naturally supports backwards compatibility as the field
is zero for the old version, matches the decoding in the new version
llvm.
