Add TryParse

[josesimoes]

Description

• Implement method in the various classes.
• Remove checks for null params in all Parse calls (this check is now carried in native).
• Rework existing NativeToInt64 and NativeToDouble with param to set throwing exception and to return conversion success/failure.
• Add Unit Tests and some rework on the existing ones where these were added.
• Fix documentation and update formatting to follow code style.
• Bump AssemblyNativeVersion 100.5.0.15.

Wit the overall changes (new feature+rework) this increases the PE size roughly ~200 bytes which seems cheap for the added value.

(temporarily disable float and double infinity tests)

Motivation and Context

• Implements a feature highly requested by the community..

How Has This Been Tested?

• Adding new units tests and improving the existing ones for Parse().

Unit Tests will fail because of the mismatch in WIN32 nanoCLR.
