meta-tpm: Fix SUMMARY/HOMEPAGE in affected recipes

To quiet the missing metadata warnings, switch DESCRIPTION to SUMMARY
in the following recipes:
- security-tpm-image
- security-tpm2-image
- packagegroup-security-tpm
- openssl-tpm-engine

and add HOMEPAGE to these recipes:
- libtpms
- swtpm
- tpm-tools
