Embedding non-pointer props

[DucaRii]

I went ahead and implemented my idea from https://github.com/neverlosecc/source2gen/issues/26

Ive opted to go with adding the offsets into the metadata of the prop for simplicity sake. Though i still had to make minor changes to the code structure in order to avoid bloat.

The conditions for whether a prop should be directly embedded are as follows

• Does it have more than 1 field and less than 13 fields (random numbers i just pulled out of my ass)
• Is it not used by more than 2 classes (some classes such as GameTime_t are used all over the place and in order to avoid bloating the dump with a bunch of embedded data i decided it'd be a good idea to only embed classes that arent frequently used)

With the changes applied a dump will now embed ~50 classes across all binaries and will look like this

// MNetworkEnable
// -> m_hModel - 0x200
// -> m_ModelName - 0x208
// -> m_bClientClothCreationSuppressed - 0x248
// -> m_MeshGroupMask - 0x2e0
// -> m_nIdealMotionType - 0x382
// -> m_nForceLOD - 0x383
// -> m_nClothUpdateFlags - 0x384
CModelState m_modelState; // 0x160

alright should be good 2 go, couldnt really think of a good name for the "usedby" constant but this one should be good enough
