Is your feature request related to a problem? Please describe.
With #660 TBL is no longer optional; conditional code/compilation configuration should be removed.

Also remove the conditional description in the doxygen documentation:

	/**
	\page cfetblugdecouple How To Remove cFE Table Services
	It is possible to build the CFE without including Table Services. This is only applicable if
	the mission does not intend to use any CFS applications that require CFE type table services, or
	if the mission intends to provide custom table services. If CFE Table Services are removed, the
	CFE makefile will no longer try to make the Table Services application and the link makefile will
	no longer include the Table Services object module in the CFE-CORE. Even if excluded from the build,
	the Table Services source and header files will remain in the CFE source tree.
	If EXCLUDE_CFE_TBL is defined (typically in the applicable *_platform_config.h file) Executive
	services will not load or shut down table services. Note this option does not effect the build
	and link of table services.
	To remove table services from the build completely, remove "tbl" from the CFE_CORE_MODULES
	in the cfe/fsw/cfe-core CMakeLists.txt directory (note this option also needs EXCLUDE_CFE_TBL defined
	or executive services will try to load it).
	Removing Table Services reduces the size of the CFE-CORE load file and also reduces the amount
	of RAM memory required to load the cFE. Each development environment will have unique savings.
	The numbers from an example default linux build are as follows:
	Size of core cFE binary load file with Table Services: 963K
	Size of core cFE binary load file w/o building Table services: 871K
	RAM used after loading cFE with Table Services: 153K
	RAM used after loading cFE w/o loading Table Services: 144M

Note - as part of fixing #950 I'm rearranging some of the cleanup logic, and the call to CFE_TBL_CleanUpApp() is currently conditional on EXCLUDE_CFE_TBL. I'd like to drop the #ifdef here as part of my upcoming change.

Here is the #ifdef I want to remove:

cFE/fsw/cfe-core/src/es/cfe_es_apps.c

Lines 1104 to 1106 in dc3d62b

	#ifndef EXCLUDE_CFE_TBL
	CFE_TBL_CleanUpApp(AppId);
	#endif

There are two other places it appears in cfe_es_objtab.c which would still need to be cleaned up, assuming we go through with this for 7.0

Note if we update to the services being modules, tbl removal/customization comes almost for free (still need to remove all the EXCLUDE_CFE_TBL occurrences). Could just make non-ops for the few calls that do exist, or customize/replace whatever is desired and replace the core module. Related to #972.
