Add vendor and image class UUID support

[tomchy]

According to the PSA Platform Security Boot Guide:

R20_PSBG_MANIFEST: Each image manifest must contain the properties specified in Figure 2. It is permitted for
additional information to be included.

The manifest (which can be interpreted as image header and additional metadata stored inside TLVs) must include:

• Image type: Specifically identifies the boot stage or peripheral. Also known as a purpose identifier. This field is not required if only one type of image is supported.
• Product class: This can refer to a vendor ID, product ID, or a more specific identifier, such as the
  Instance ID.

This PR introduces two identifiers to meet those requirements:

• Image class ID, defined as RFC 9562 UUID Version 5, that may contain all: image type and product type values as input.
• Image vendor ID, defined as RFC 9562 UUID Version 5, that provides the namespace for the image class ID, so two devices with the same type/product name will have different image class UUIDs.
