[Local GC] Obtaining configuration information (#11379)

* [Local GC] Skeleton for GC configuration

* Initial tweaks after design feedback:
    1) Use string keys instead of enums. Upon receiving a string key,
    the EE looks at it and, if it's something that comes from startup
    flags, responds using the startup flag information. Otherwise, it
    forwards the string onto CLRConfig.
    2) Add a mechanism for getting string configuration values from the
    EE. This includes adding a RAII wrapper around strings so that they
    are freed correctly.

* Remove uses of g_pConfig from the GC and replace with GCConfig

* Use the GCConfig system for the GC log

* Fix poorly-named parameter

* Add documentation and caching of bool and int configs obtained from the EE

* Remove AppDomainLeaks as dead code

* Remove GC trace configs as dead code

* Repair unix build

* Fix an issue where we started the GC in the wrong latency mode

* Fix the unix build

* Pipe GCRetainVM configuration to the GC

* Dead code removal in the GC sample

* EEConfig -> GCConfig for heap verification constants in the GC

* Populate config information for bools and ints eagerly at startup

* Initialize g_theGCToCLR before initializing GCConfig

* Propegate HoardVM config to the GC

* Fix an incorrect comment
