Tess Strickland a36d17730a Reland "[vm] Allow BaseWriteStream::WriteFixed to be used at unaligned positions."
Fixes errors introduced by adding PRINTF_ATTRIBUTE to
BaseWriteStream::Printf due to attempting to print a
compiler::target::uword using the format for uword.

Original description:

For snapshot writing, we generally only have aligned writes so the old
methods worked well, but in some formats (like DWARF) we're not
guaranteed to have aligned writes and so had to use WriteBytes.
Instead, have WriteFixed call WriteBytes and replace any other uses of
WriteBytes(&value, sizeof(value)) with WriteFixed(value) instead.

Also makes the following additional changes:

* Expose WriteByte(value), instead of forcing use of
  WriteFixed<uint8_t> or Raw<1,T>::Write to get the same behavior.

* Rename Print/VPrint to Printf/VPrintf, so methods taking format
  strings are named consistently with others in the codebase.

* Add format string checking to Printf when supported.

* Add AddString() for non-formatted string writing.
