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.
