Optimize: Use measureText instead of doLayout.
With this CL, measureText is used for getRunAdvance,
getOffsetForAdvance and line breaking.

Allow clusters to start with zero-width characters
The logic in getRunAdvance() assumed that any zero-width character was
part of the preceding cluster, which is valid most of the time. However,
characters such as ZWNBSP (U+FEFF) renders as a zero width glyph
and is also a grapheme cluster boundary. This patch adds a clause to
handle that case.

Fix: getOffsetForAdvance can return worng offset.
searchStart was passed to getRunAdvance, but it can be
different from the start that has been used to initialize
Layout object. As a result, wrong index could be used in
getRunAdvance.

Use context start correctly in getRunAdvance
We were not taking context start into account when deciding whether
to split a ligature, which was causing inconsistent behavior. This
patch consistently references the widths array relative to the start
of the context.
