Revert of Fix SkPaint::measureText for stroked hairline text (https://codereview.chromium.org/335603003/)

Reason for revert:
Caused many shadertext GM failures

Original issue's description:
> Fix SkPaint::measureText for stroked hairline text
>
> SkPaint::measureText and text drawing used different criteria for
> determining whether text should be drawn as paths or not.
>
> Adds tests glyph_pos_(h/n)_(s/f/b) to test the text rendering and the glyph
> positioning in the rendering. Mainly added in order to define what is the
> expected text rendering when hairline stroke is used with various transform
> options.
>
> The testcase also tries to note or highlight the fact that SkPaint::measureText
> is not expected to produce intuitively matching results when compared to a
> rendering, if the rendering is done so that the device ends up having a device
> transform.
>
> This fixes the glyph_pos_h_s (hairline, stroked) test-case.
>
> Ignore shadertext2_pdf-poppler.png gm on
> Test-Ubuntu13.10-ShuttleA-NoGPU-x86_64-Debug temporarily, as that fails.
