Use cached delegates to set property values rather than SetValue

[Mpdreamz]

Using the following Fake context to generate 10,000 items:

FakerWithRules = new Faker<Project>()
    .CustomInstantiator(f=> new Project())
    .RuleFor(p=>p.Id, f => f.IndexGlobal)
    .UseSeed(1337);

Old (SetValue):

Method	Mean	Error	StdDev	Gen 0	Gen 1	Gen 2	Allocated
Generate_WithRules	6.770 ms	0.0624 ms	0.0584 ms	265.6250	109.3750	31.2500	1.55 MB

New (Cached setter delegate):

Method	Mean	Error	StdDev	Gen 0	Gen 1	Gen 2	Allocated
Generate_WithRules	4.046 ms	0.0251 ms	0.0235 ms	164.0625	93.7500	31.2500	960.09 KB
