  [JITLink][NFC] Add TableManager to replace PerGraph...Builder pass

This patch add a TableManager which reponsible for fixing edges that need entries to reference the target symbol and constructing such entries.

In the past, the PerGraphGOTAndPLTStubsBuilder pass was used to build GOT and PLT entry, and the PerGraphTLSInfoEntryBuilder pass was used to build TLSInfo entry. By generalizing the behavior of building entry, I added a TableManager which could be reused when built GOT, PLT and TLSInfo entries.

If this patch makes sense and can be accepted, I will apply the TableManager to other targets(MachO_x86_64, MachO_arm64, ELF_riscv), and delete the file PerGraphGOTAndPLTStubsBuilder.h
