Problem: If a line has "right" & "below" virtual text properties,
where the "below" property may be stored first due to lack of
ordering between them, then the line height is calculated to
be 1 more and causes the cursor to far over the line.
Solution: Remove some unnecessary setting of a
`next_right_goes_below = TRUE` flag for "below" and "above"
text properties. (Dylan Thacker-Smith)
I modified a regression test I recently added to cover this case,
leveraging the fact that "after", "right" & "below" text properties are
being stored in the reverse of the order they are added in. The
previous version of this regression test was crafted to workaround this
issue so it can be addressed by this separate patch.

Problem: When a line is truncated just before 'after'/'right' virtual
text and the line also has 'below' virtual text, then the
'below' virtual text would not be displayed, depending on the
order these text properties were added.
Solution: In the loop to make text properties active, skip instead of
break for 'after'/'right' virtual text properties that are
ignored due to truncation, so following 'below' text
properties can still be made active.
Similarly, a loop is needed to determine if a text property
follows at the end of the screen. (Dylan Thacker-Smith)

Problem: The if branch to set `text_prop_follows` was both checking if
it was at the end of the buffer text line or if it was at the
end of the screen line, but the former being true skipped
a guard condition in the latter to only consider 'below'
virtual text to follow. `text_prop_follows` being improperly
set caused it to skip a conditional block to break at the end
as well as one to move `ptr` to the end of the text line,
while repeated for each following line of the window.
Solution: Move the check for whether 'below' virtual text should follow
so it is also used when at the end of the buffer text line.

Problem: `gM` would include outer virtual text and its padding when
getting the line length used to calculate the middle of the
line, putting the cursor much closer to virtual text lines.
Solution: Exclude outer virtual text in getting the line length for
`gM`, so that virtual text doesn't influence where the cursor
is moved to (Dylan Thacker-Smith).

Problem: `gj`/`gk` was updating the desired cursor virtual column to
the outer virtual text, even though the actual cursor position
was moved to not be on the virtual text, leading the need to
do an extra `gj`/`gk` to move past each virtual text line.
(rickhowe)
Solution: Exclude the outer virtual text when getting the line length
for moving the cursor with `gj`/`gk`, so that no extra
movement is needed to skip over virtual text lines.

Problem: The cursor screen row was incorrectly being calculated when the
cursor follows a 1 character text_align 'below' virtual text line,
resulting in the cursor being shown on the wrong line.
This was caused by a cell size of 2 instead of 1 being used for the EOL
character, which propagated to the calculation of space for putting the
'below' virtual text on its own line. (rickhowe)
Solution: Fix the size used for the EOL character in calculating the
cursor's screen position (Dylan Thacker-Smith)

Problem: Virtual text with text_align 'right'/'below' wasn't being
used when a non-virtual text property overlaps with the end of
the line. This was because the non-virtual text property had a
higher priority, preventing the virtual text from being used.
Solution: Fix the sorting of text properties so virtual text properties
have a higher priority than non-virtual text properties.

Problem: text-property without type errors when joining
Solution: count all text-properties, with or without type
before joining lines
Error when joining lines with text properties without a proper type
When joining lines, we need to consider all text properties that are
attached to a line, even when those text properties are invalid and do
not have a type attached to them.
However, since patch v9.0.0993
(commit: 89469d157a)
those text properties won't be counted when joining lines and therefore
this will cause the adjustment for text properties on joining to go
wrong (and may later cause SIGABRT with an invalid free pointer)
I am not sure, why the condition to not count text properties with a
valid type was added in patch v9.0.993, because no test fails if those
condition is removed. So let's just remove this condition and add a test
that verifies, that we are able to join lines, even when the text
properties attached to it do not have a valid type.
