Introduced shared library injection as dumper load method.

Try to load custom dumpers using shared library injection
first as it is faster and does not rely on the symbol
for LoadLibrary being known to the debugger. Keep
call loading as fallback. Move the rest of the initalization
to the first dumper call, removing the need to break at main().
