Genproj updates for BCL build in Windows Visual Studio (mono/mono#7755)

This batch of commits makes further updates to our support for building the BCL using msbuild (Visual Studio, to be specific).

* Generates a single sln and set of csproj files with support for all of our build profiles (orbis, monodroid, net_4_x, etc)
* Project configuration selector (in VS or as parameter to msbuild) can be used to select which profile to build
* Includes partial dependency information so that culevel and jay are compiled before the rest of the sln (this keeps pre/post events from from failing on first build)

As of this rev things are working pretty good, but a lot of the measures I took here are temporary so I'd appreciate thoughts on how to go about them. The hard-coded System.Web -> Culevel dependency feels gross, for example - I kind of want to go through and build an automatic solution for it but I'm not sure it's necessary.

Implements mono/mono#6858

---

* Checkpoint: Generate single .csproj file with conditional item/property groups

* Checkpoint: Updates to csproj and sln generation to support building specific profiles

* Move targets file in csproj template so that it isn't evaluated before all properties are set

* Checkpoint profile fallback (use net_4_x if project does not have appropriate profile)

* Use in-process cache for project guids to fix bug where many guids were being generated. Fix profile fallback.

* Clean up unnecessary debug writelines

* genproj error fixes

* Remove duplicate gacutil entry from makefile to fix order.xml corruption. Cleaner project names in msbuild sln. Compile genproj before generating inputs.

* Delete genproj.exe at beginning of update-solution-files because otherwise syntax errors will cause an old version to be used silently
Cleaner messages from genproj

* Hard-code the guid for culevel and add it as a dependency for system.web

* Bug fixes

* sln files are sensitive to whitespace format

* Don't generate pointless solution configurations if we have no information for them

* Updates based on PR feedback
