Fix CMakeLists.txt for Android builds

[ankitkapur]

Add

if(ANDROID)
  list(APPEND SRCS
    offline/OfflineStorage_Room.cpp
  )
else()
list(APPEND SRCS
    offline/OfflineStorage_SQLite.cpp
  )
endif()

For lib/CMakeLists.txt for Droid compilation.

[ankitkapur]

list(APPEND SRCS
    pal/posix/NetworkInformationImpl.mm
    # TODO: this unit below needs to be deprecated and removed
    ../third_party/Reachability/ODWReachability.m
)

//Add this elseif block
elseif(ANDROID)
list(APPEND SRCS
http/HttpClient_Android.cpp
http/HttpClient_Android.hpp
pal/posix/NetworkInformationImpl.cpp
)
else()
list(APPEND SRCS
http/HttpClient_Curl.cpp
http/HttpClient_Curl.hpp
pal/posix/NetworkInformationImpl.cpp
)

Add this OR
if(PAL_IMPLEMENTATION STREQUAL "WIN32" OR ${CMAKE_SYSTEM_NAME} STREQUAL "Android")

Regarding including the correct offline storage files, isn't it is already handled here -

cpp_client_telemetry/lib/android_build/maesdk/src/main/cpp/CMakeLists.txt

Lines 107 to 115 in b35fe2d

	if (USE_ROOM)
	add_definitions("-DUSE_ROOM")
	list(APPEND SRCS ${SDK_ROOT}/lib/offline/OfflineStorage_Room.cpp)
	else()
	list(APPEND SRCS
	${SDK_ROOT}/lib/offline/OfflineStorage_SQLite.cpp
	${SDK_ROOT}/sqlite/sqlite3.c
	)
	endif()

So Room DB files should be included only if build with USE_ROOM. This way, it would be possible to use SQLiteDB in android too if USE_ROOM is not set.

Similar reasoning for HTTP library -

cpp_client_telemetry/lib/android_build/maesdk/src/main/cpp/CMakeLists.txt

Lines 117 to 121 in b35fe2d

	if (USE_CURL)
	list(APPEND SRCS ${SDK_ROOT}/lib/http/HttpClient_Curl.cpp)
	else()
	list(APPEND SRCS ${SDK_ROOT}/lib/http/HttpClient_Android.cpp)
	endif()

@ankitkapur - Do you have plan to work on this, or can we close it based on reasoning given in above comments ?
