[nfc]Make InstrProfSymtab non-copyable and non-movable (#86882)
- The direct use case (in [1]) is to add `llvm::IntervalMap` [2] and the allocator required by IntervalMap ctor [3]
to class `InstrProfSymtab` as owned members. The allocator class doesn't have a move-assignment operator;
and it's going to take much effort to implement move-assignment operator for the allocator class such that the
enclosing class is movable.
- There is only one use of compiler-generated move-assignment operator in the repo, which is in
CoverageMappingReader.cpp. Luckily it's possible to use std::unique_ptr<InstrProfSymtab> instead, so did the change.
