Rework usages/naming of configuration macros [part 1] (#2793)

There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.

Main changes:

* Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format.
* The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins.
* Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format.
* The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins.
* Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
* All options (in this change) can have a value of 0 or 1.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
  JERRY_REGEXP_STRICT_MODE is set to 0 by default.
* Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now
  it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point
  number.
  By default the 64-bit floating point number mode is enabled.
* All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to
  test if the feature is enabled or not.
* Added/replaced a few config.h includes to correctly propagate the macro values.
* Added sanity checks for each macro to avoid incorrectly set values.
* Updated profile documentation.
* The CMake feature names are not updated at this point.
