This is an ongoing series of commits that are reformatting our
Python code. This catches the last of the python files to
reformat. Since they where so few I bunched them together.
Reformatting is done with `black`.
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.
If you run into any problems, post to discourse about it and
we will try to help.

Breakpoint deletion in visual studio is currently implemented by
iterating over the breakpoints we want to delete, for each of which we
iterate over the complete set of breakpoints in the debugger instance
until we find the one we wish to delete. Ideally we would resolve this
by directly deleting each breakpoint by some ID rather than searching
through the full breakpoint list for them, but in the absence of such a
feature in VS we can instead invert the loop to improve performance.
This patch changes breakpoint deletion to iterate over the complete list
of breakpoints, deleting breakpoints that match the breakpoints we
expect to delete by checking set membership. This represents a
worst-case improvement from O(nm) to O(n), for 'm' breakpoints being
deleted out of 'n' total. In practise this is almost exactly 'm'-times
faster, as when we delete multiple breakpoints they are typically
adjacent in the full breakpoint list.

These tests were spuriously failing on Windows due to path separators getting
flipped from `/` to `\\` in various parts of dexter:
test_add_breakpoint_with_source_root_dir
test_get_step_info
test_get_step_info_no_source_root_dir
Tested on Windows and Linux.

This patch allows a visual studio solution file to be passed directly
into Dexter, instead of using a pre-built binary and a small internal
solution file with template arguments. This is primarily to allow
launching an application that has specific launch configuration
requirements, without needing all the details of this configuration to
be built directly into Dexter or adding a config file that simply
duplicates existing settings in the VS solution.

Fixes issue found on greendragon buildbot, in which an incorrectly
indented statement following an if block led to entire frames being
dropped instead of simply filtering unneeded watches.
This reverts commit 1f44fa3ac17ceacc753019092bc50436c77ddcfa.
Currently, Dexter's model for fetching watch values is to build a list of
expressions to watch before running the debugger, then evaluating all of them at
each breakpoint, then finally looking up the values of these expressions at each
line they were expected on. When using dexter on a large project while watching
many different expressions, this is very slow, as Dexter will make a massive
number of calls made to the debugger's API, the vast majority of which are not
being used for anything. This patch fixes this issue by having Dexter only
evaluate expressions at a breakpoint when it will be used by a Dexter command.
