readelf: Add RISC-V DWARF register aliases
This allows DWARF debugging output to use the common register
mneumonics, such as ra, sp, or t0.
DWARF registers 0-31 are mapped to the 32 general purpose registers,
which are then followed by the 32 floating point registers.

libdwarf: Use the cached strtab pointer when reading string attributes.
Previously we would perform a linear search of the DWARF section
list for ".debug_str". However, libdwarf always caches a pointer to
the strtab image in its debug descriptor. Using it gives a modest
performance improvement when iterating over the attributes of each
DIE.

elfcopy: Provide a size hint when creating the section string table.
Use the input file's .shstrtab size as the hint if it exists. This
gives a small performance improvement when processing files with
many sections.
