Richard Smith 85d5b40429 Clean up interface of node block stack after recent changes. (#3229) 
- `Peek()` no longer returns a useful value, because we often don't
allocate a `NodeBlockId` until we finish building the block. Remove it
and update both its callers.
- Rename `PeekForAdd()` to `PeekOrAdd()` since it's no longer used to
get a block ID to add elements into.
- `PushForAdd()` was unused. Remove it.
- Add `NodeBlockStack::AddNode` to combine the operations of adding a
node and inserting it into a block.

Richard Smith a66f35e92c Store contents of incomplete node blocks on the node block stack. (#3223) 
`SemIR` now only stores complete blocks, and placeholders for blocks
where we need a block ID before we know the block contents.

This is a preparation step towards the new node block allocation design.

Richard Smith 9ba1669472 Remove Check::Context::AddNodeToBlock and SemIR::File::AddNode. (#3221) 
Nodes are now only ever added to the current block in the node block
stack.

This is a preparation step towards the new node block allocation design.

Jon Ross-Perkins 1c748c0f14 Split semantics into check and sem_ir directories (#3176) 
Continuing along with #3070. Note this is just a file rename, with BUILD
edits; every file previously in semantics/ should show as moved (except
maybe BUILDs, which split).
