  [LLDB] Impove ObjectFileELF's .dynamic parsing and usage. (#101237)

This patch improves the ability of a ObjectFileELF instance to read the .dynamic section. It adds the ability to read the .dynamic section from the PT_DYNAMIC program header which is useful for ELF files that have no section headers and for ELF files that are read from memory. It cleans up the usage of the .dynamic entries so that ObjectFileELF::ParseDynamicSymbols() is the only code that parses .dynamic entries, teaches that function the read and store the string values for each .dynamic entry. We now dump the .dynamic entries in the output of "image dump objfile". It also cleans up the code that gets the dynamic string table so that it can grab it from the DT_STRTAB and DT_STRSZ .dynamic entries for when we have a ELF file with no section headers or we are reading it from memory.
