Extract data reading logic from constructors

Constructors, given their nameless nature, should not perform any unexpected heavy operations. I believe the I/O operations that are currently being performed in constructors should be extracted to either separate helper classes, or static factory methods.

This is in a way related to #2. That task also mentions refactoring logic of the code responsible for parsing structures.

Create a TreeView control displaying module metadata

The goal here is to have a TreeView-based control that displays the name of module as a top-level node. Module metadata can be displayed as children nodes. My suggestion is to have a hierarchy like this: <module_name> -> Metadata -> <metadata_table_name> -> <metadata_table_row_index> -> <metadata_table_row_column_name_and_value>.

Add means of lock-free module reading

For an additional performance boost, we should consider dropping the locks in SharedReader to enable parallel disassembly.
We're reading the whole file into memory, so reading it from a FileStream byte by byte doesn't make much sense now.

Handle RVA==0 in ClrMethod reader

Currently, a ClrMethod with RVA==0 will have its MaxStack set to 0 and body set to an empty array. In the future it may be necessary to set a flag on such method to distinguish it from other methods.

Add reading MethodDef metadata table

ECMA-335: II.22.26 MethodDef : 0x06
This will bring us closer to being able to read body of methods. In fact, the RVA column of the MethodDef table points to the COR_ILMETHOD structure.

Ensure every metadata table has a parsing test

• FieldRow
• ModuleRow
• TypeDefRow
• TypeRefRow

Create a type facilitating reading PE structures described by data directories

Inspired by this comment under my recent PR. It would be nice to have a helper type/method allowing to read PE data structures described by data directories by providing data structure name--for example, ClrHeader. For a list of all PE data directories describing PE sections, see docs.

Research what are the next steps to read method bodies

We need to have our own equivalent of MethodBase.GetMethodBody. Research has to be done to find out what are the next steps to be able to read method bodies.

This ticket tracks ongoing work to implement such functionality.

Separate metadata tables reading logic from the actual data types

It would be nice to separate metadata tables reading logic from types holding the actual data. This way, the = null! nullability warning silencer hack could be avoided when declaring properties of reference type.

Add reading COR_ILMETHOD

Create types enabling reading the COR_ILMETHOD structure. The goal here is to design classes to represent the layout of COR_ILMETHOD, and to add a helper (method?) that given RVA of COR_ILMETHOD, will read the struct, parse it, and return its object model representation.

Details about COR_ILMETHOD can be found in ECMA-335, §II.25.4.
