Add some quirk and versioning flags and change some preprocessor symbols into fields of CORINFO_EE_INFO.

The quirk flags--CORJIT_FLG2_JIT32_QUIRKS and CORJIT_FLG2_JIT64_QUIRKS--are passed by the EE to request that the JIT
generate appropriately compatible executable code. These flags are only passed on x86/Windows and x64/Desktop/Windows,
respectively.

Version numbers for GC and EH info have been added to CORINFO_EE_INFO. The EE sets these versions to indicate the
formats of the aforementioned data that it supports.

CORINFO_PAGE_SIZE and MAX_UNCHECKED_OFFSET_FOR_NULL_OBJECT have been converted to fields on CORINFO_EE_INFO.
