Adjusting half-blocks, quadrants,... coordinates to unify mosaics (#727)

This update adjusts the points coordinates of some previously existing
blocks/mosaics characters to fit them in the same grid as used by
octants and eights.
This is required because the new octants and eights from Symbols for
Legacy Computing do not duplicate existing patterns and expect those
existing one to join perfectly with them to provide the whole set of all
possible pseudopixels mosaics.

This update verifies and adjusts the existing characters that are now
required to join seamlessly with the extended pseudo-pixels mosaics
introduced with the symbols for legacy computing.
Some of the existing characters were not proper mosaics, most notably
`▞`, where the two black rectangles overlap because they don't use the
same y coordinates.
This shouldn't happen as all the mosaics are supposed to fit precisely
on a unified grid.
Only a few characters required adjustments, but this PR also documents
all the glyphs that have been checked to ensure alignments of all the
mosaic characters.

**BLOCKS:**
`U+00A0` nbspace : already correct
`U+2588` fullBlock & fullBlock.stypo : already correct (used as
reference bounding rectangle for all pseudopixels mosaics)

**HALF-BLOCKS:**
`U+2580` upperHalfBlock & upperHalfBlock.stypo : y=50% fixed from 707 to
873 (gdi) and 710 (stypo)
`U+2584` lowerHalfBlock & lowerHalfBlock.stypo : already correct
(confirming upperHalfBlock y=50% was wrong)
`U+258C` leftBlock & leftBlock.stypo : already correct
`U+2590` rightBlock & rightBlock.stypo : already correct

**QUADRANTS:**
`U+2596` lowerLeftBlock & lowerLeftBlock.stypo : already correct
(confirming all other corrections above and below)
`U+2597` lowerRightBlock & lowerRightBlock.stypo : y=50% fixed from 707
to 873 (gdi) and 710 (stypo)
`U+2598` upperLeftBlock & upperLeftBlock.stypo : y=50% fixed from 707 to
873 (gdi) and 710 (stypo)

`U+259E` upperRightAndLowerLeftBlock & upperRightAndLowerLeftBlock.stypo
: Some y=50% fixed from 707 to 873 (gdi) and 710 (stypo), some were
already correct
`U+259F` upperRightAndLowerLeftAndLowerRightBlock &

from 534 to 535 (rounding unification for all Eights) for GDI, stypo was

was correct
`U+2594` upperOneEighthBlock & upperOneEighthBlock.stypo : y fixed from
1887 to 1888 (rounding unification for all Eights) for GDI, stypo was

This fixes the inconsistent alignments problem explained in issue #644,
and ensures unified grid coordinates with PR #708 and #723.

## Validation Steps Performed
Based on purely mathematical grid coordinates already used for octants,
checked visually in VTT, Terminal Preview 1.20.10822.0 and Canary
1.21.240424002-llm, and Visual Studio editor.

Note there is another related issue that impacts some of those
characters, but this PR at least provides the correct glyphs and
improves the situation. I believe the remaining alignment issue to be a
problem in Terminal itself as it works perfectly in Visual Studio
editor, and the original Cascadia Mono 2111.001 exhibits the same issue.
More details about this in #644.
Having the proper coordinates at least ensures they won't induce in
error someone trying to fix the Terminal rendering and expecting the
alignments to work with a font using inconsistent glyphs coordinates. A
believe this PR to be a step in the right direction.

Closes #644
