Tess Strickland fa03ee7782 [vm] Create a common base class for TextBuffer/ZoneTextBuffer.
Generally, methods that take a *TextBuffer pointer do not care how the
internal buffer is allocated, and so they could be used for either if
both were subclasses of a base class that contained the printing
methods.  This CL makes that base class, and now TextBuffer and
ZoneTextBuffer now share the exact same set of methods for printing to
the internal buffer.

Since the base class is in platform, this does mean dropping the
overload of AddString for Dart String objects that was part of
ZoneTextBuffer.  Instead, this CL just adds an intermediate call to
ToCString() for the small number of callers that used the overload,
keeping the printing interface the same for both.

In addition, one use of TextBuffer that then re-allocated the buffer
contents into the zone manually has been replaced with a ZoneTextBuffer
instead.

Aart Bik aceefaf846 [dart/vm]: fix bug in TextBuffer capacity
Rationale:
Ensuring capacity computation was off by one (due to trailing '\0')
if the initial buffer size was zero. Granted, this can only happen
after a Steal(), but since API did not exclude reuse after this
operation, it is better to just handle this than crash.

Ryan Macnak 971f4845d7 [build] Remove last platform -> vm and bin -> vm dependencies. Fix some ODR violations.
Change some static_libraries to source_sets to make ODR violations link-time errors.

This is needed to enable (stop suppressing) -fvisibility=hidden in Fuchsia product builds.

Alexander Markov f6d6766920 [VM] Restore disassembler in flutter/profile (dart/release) mode
This CL restores disassembler in precompiled mode after it was removed
in 8cb752f73b.
Without disassembler observatory is not able to show assembly code
in 'flutter run --profile' mode.

This CL also pulls BufferFormatter out of il_printer.h/.cc as it is also
used in disassembler.
