[LLDB][NativePDB] Estimate symbol sizes (#165727)
In #165604, a test was skipped on Windows, because the native PDB plugin
didn't set sizes on symbols. While the test isn't compiled with debug
info, it's linked with `-gdwarf`, causing a PDB to be created on
Windows. This PDB will only contain the public symbols (written by the
linker) and section information. The symbols themselves don't have a
size, however the DIA SDK sets a size for them.
It seems like, for these data symbols, the size given from DIA is the
distance to the next symbol (or the section end).
This PR implements the naive approach for the native plugin. The main
difference is in function/code symbols. There, DIA searches for a
corresponding `S_GPROC32` which have a "code size" that is sometimes
slightly smaller than the difference to the next symbol.
