Add support to define function signatures in gamedata
...
A "Functions" section is parsed in gamedata files that allow you to define the signature of functions including metadata like the calling convention and specifying the register an argument is passed in.
A new native DHookCreateFromConf can be used to setup a hook or detour from one of that function sections in the "Functions" section.

Fix passing this pointer to callback even if the detour was setup to ignore it

The this pointer was always passed to the plugin callback if the calling convention was a thiscall. Even if the plugin author set the this pointer type to ThisPointer_Ignore.

Fix saving arguments in custom registers in combination with arguments on the stack
...
If a function was optimized to only pass one parameter in a register, but still pass other parameters on the stack, save the registers at the correct offset in the buffer.

Fix assert when the pre-hook was fired, but the post hook was skipped
...
The post hook would have cleared the esp value from the return address map, but there seems to be a case where the post hook isn't called, but the function gets called with the same esp again. This is probably just masking a different error :(

Add support for custom calling convention passing arguments in registers
...
If the compiler decided to pass an argument in a register on an internal function instead of pushing it on the stack to save time, allow us to specify the register the parameter is going to be in.
DHookAddParam received another parameter to set the register.

Fix not clearing return address cache after use
...
The esp pointer wasn't removed from the map after the function was called and the original return address was retrieved.
If the same function was called again with the same esp this would fail due to there already being an (old) return address associated with the esp.
