OpenGL: Fix shader compilation on Ubuntu 18.04

Browse source 
Previously, we were always adding a #version 150 directive to shaders
when the GLSL version was higher than 1.2, which could cause compilation
to fail on platforms with GLSL versions between 1.2 and 1.5.

Develop
=======
Change
------
The JUCE_GLSL_VERSION preprocessor definition has been removed.
Possible Issues
---------------
Code which used this definition will no longer compile.
Workaround
----------
Use OpenGLHelpers::getGLSLVersionString to retrieve a version string which is
consistent with the capabilities of the current OpenGL context.
Rationale
---------
A compile-time version string is not very useful, as OpenGL versions and
capabilities can change at runtime. Replacing this macro with a function allows
querying the capabilities of the current context at runtime.
Change
------
The minimum support CMake version is now 3.15.
