Document MSBuild properties related to static web assets

[danroth27]

It looks like we have some MSBuild properties for configuring static web assets that aren't documented anywhere I could find. For example, some users have been looking for a way to disable fingerprinting and have discovered the StaticWebAssetFingerprintingEnabled and StaticWebAssetsFingerprintContent properties, but these don't seem to be mentioned anywhere in the docs, so it's not clear what their semantics are. Another example is DisableBuildCompression. There may be others.

@javiercn Can you help out with listing the related properties for managing static web assets that should be documented for public use?
