Add missing ELF section support

[xoofx]

The ELF reader/writer is missing some features:

• Dynamic Linking Table (SHT_DYNAMIC)
• Version Symbol Table (SHT_VERSYM)
• Version Needs Table (SHT_VERNEED)
• New relative relocation table RELR (SHT_RELR)

These sections are currently loaded as ElfCustomSection but should have their own ElfXXXTable (e.g ElfDynamicLinkingTable, ElfVersionSymbolTable...)

Does the Group Section works?
