[M67 Dev][Tizen] Migrate version and profile related changes

This CL introduces defining the version automatically depending
on build configuration.

The double-quotes of numbers in script are removed to properly
handle a comparison operation.

Also, this removes legacy tizen version conditions such as 2.3
or 2.4 and unused legacy tizen profile dependencies.

There were tizen or chromium version definations in xml or pc file
like below.
>> in chromium-efl_v3.0.xml or ubrowser_v3.0.xml
>> <manifest xmlns="http://tizen.org/ns/packages" api-version="3.0" ...

Whenever tizen version is upgraded, the file chromium-efl_vX.X.xml
or ubrowser_vX.X.xml have been manually added or removed.

Although it works, it is not elegant and other parts of the source
base do not use similar practice.

This introduces automatically defining the current version, depending
on build system configuration and removes unsued configuration files.

This CL also updates chromium version to 67.3396.0.

This CL also refactors xml related things as per platform requirement.
