New Data Types added in vSphere 7.0 U1 and U2 missing from vmodl.db

[agrare]

Describe the bug
RbVmomi is missing data types added in vSphere 7.0 U1 and U2 causing "unknown VMODL type X" errors

To Reproduce
Steps to reproduce the behavior:

1. Connect to a vSphere 7.0.1 or 7.0.2
2. Issue a request for which the response will return a missing datatype (e.g. VsanDatastoreInfo)
3. 💥

Expected behavior
RbVmomi should be able to deserialize datatypes from the current version of vSphere

Platform:

• OS: Debian 11
• RbVmomi Version: master 32955d9
• Ruby Version: ruby 2.7.3p183 (2021-04-05 revision 6847ee089d) [x86_64-linux-gnu]

Additional context
The list of missing types:

• ClusterComputeResourceVcsSlots
• DesiredSoftwareSpecComponentSpec
• FeatureEVCMode
• HttpNfcLeaseProbeResult
• VirtualMachineConnection
• VirtualMachineMksConnection
• VMwareDvsMtuCapability
• VsanDatastoreInfo
• HostSevInfo
• HostTpmNvTagEventDetails
• HostTrustAuthorityAttestationInfo
• GuestInfoCustomizationInfo
• vslmVClockInfo

I'm happy to work on a PR to add these data types by building them by hand using the U2 wsdl, or if one of the VMware maintainers is able to re-run your generator on the current vmodl file.
