[MC,AArch64] Create mapping symbols with non-unique names
Add `createLocalSymbol` to create a local, non-temporary symbol.
Different from `createRenamableSymbol`, the `Used` bit is ignored,
therefore multiple local symbols might share the same name.
Utilizing `createLocalSymbol` in AArch64 allows for efficient mapping
symbol creation with non-unique names, saving .strtab space.
The behavior matches GNU assembler.
