Update all calls of ReadString to include the third parameter to have a max read. Add an Elf creation benchmark since this function is on the elf creation path.

Optimize Memory::ReadString

This function is responsible for majority of CPU time in prefetto.

Reduce the number of memory reads (don't read strings byte-by-byte).

Update all calls of ReadString to include the third parameter to have
a max read.

Add an Elf creation benchmark since this function is on the elf
creation path.

Test: libunwindstack_unit_test
