DevTools: [Icons] normalize icon sizes

As a result of this patch, we have:
- 65 icons of 28x24 size (belong to "large" icons)
- 24 icons of 10x10 size (belong to "small" icons)

The rest of the icons belong to "medium" icons and will
be normalized to be 16x16.

DevTools: minor cleanup for the icons

This is a minor cleanup for the icons before re-arranging a spritesheets
by their sizes.

This patch:
- kills unused icon from toolbarButtonGlyphs.svg
- kills smallicon-clear-input since its a dupe of smallicon-gray-cross-hover
- kills largeicon-block since it is a left-over after the icon removal
- fixes size of largeicon-chevron to be 28x24

DevTools: re-arrange icons into spritesheets by their size

This patch re-arranges icons into spritesheets by their sizes.
Instead of having three spritesheets:
- smallIcons.svg
- resourceGlyphs.svg
- toolbarButtonGlyphs.svg

We now have another three spritesheets, where icons are put
according to their size:
- smallIcons.svg - 10x10 icons
- mediumIcons.svg - 16x16 icons
- largeIcons.svg - 28x24 icons

Each svg spritesheet has a nice grid which helps to align icons:

Icon extraction and re-assembling is done via the
http://github.com/aslushnikov/devtools-icon-extractor

Regarding the binary size of all produced PNG assets, this patch
reduces devtools bundle by ~1.5kb.

DevTools: normalize medium icons

This patch normalizes sizes for mediumicons, making them all 16x16.

This patch is only possible with https://crrev.com/2772153002/: it makes
sure that icons have enough space around and thus could be set more width
and height.

DevTools: use chess-like icon positions

This patch:
- moves icons from {x, y, width, height} coordinates into
  chess-like coordinates. Position 'a1' means bottom-left corner,
  and position 'a8' means 1st column 8th row.
- removes spritesheet image sizes from inspectorCommon.css. This
  turned out to be possible since icon's background/mask-image
  always have default size of the image.

This solves multiple issues:
- it's easy to convert between icon coordinates and spritesheets.
  Chess-like coordinate systems are embedded into SVGs:
  http://imgur.com/a/YcSSs
- it discourages abusing of icon sizes - icon could occupy the
  whole cell only
- resizing spritesheet is as easy as changing its size in inkscape

Performance-wise, this change doesn't impact time to create icon in
a noticeble way. Before this patch, creating all 107 icons was
taking ~3ms on my MacBook Pro 2015. With this patch, the time
didn't change.
