Add Size and Alignment on type/field hover

[Caleb-o]

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Both Golang and Rust show the size and alignment of types. Since C3 is a lower level language, it would be useful to have this information available on hover, instead of needing to use something like reflection.

Describe alternatives you've considered
Reflection could be used, but it is not as convenient

Additional context
Type:

Field (from Josh):

Go's LSP Gopls may be a helpful reference, here's the code:

Is there any reference on C3 about what size every type uses?

[Caleb-o]

There is a list on basic types that shows the bit size of primitives

[Caleb-o]

As a note, you also need to take alignment into account for padding in structs. Unions are just the size of their largest item. To verify that types are calculated properly, you can use sizeof from type properties to validate the size is correct.

@pherrymason how is this going? There was some progress posted in the tooling channel of discord, but haven't heard anything since. Did you get stuck or did life start doing life things and you've been busy?

Sorry, I've been more busy lately and could not advance with this
