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.

After the default PDB plugin changed to the native one (#165363), this
test failed, because it uses the size of public symbols and the native
plugin sets the size to 0 (as PDB doesn't include this information
explicitly). A PDB was built because the final executable in that test
was linked with `-gdwarf`.

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Currently, SBTarget::SetModuleLoadAddress does not accept large slides
needed to load images in high memory. This function should always have
taken an unsigned as the slide, as it immediately passes it to
Target::SetSectionLoadAddress which takes an unsigned.
This patch adds an overload and exposes that to SWIG instead of the
signed variant. I've marked the signed variant as deprecated and added
check that the slide is positive.

In API tests, replace use of the `p` alias with the `expression` command.
To avoid conflating tests of the alias with tests of the expression command,
this patch canonicalizes to the use `expression`.

SectionLoadList has a section-to-address map (m_sect_to_addr) and
an address-to-section map (m_addr_to_sect). When the load address
of a section is updated, the old entry from m_addr_to_sect would
never be cleared, resulting in incorrect address-to-section address
lookups from that point forward.
