SPDX exceptions list incomplete in src/vcpkg/spdx-exceptions.inc

[ycollet]

The SPDX exceptions list embedded in src/vcpkg/spdx-exceptions.inc appears to be outdated and incomplete compared to the official SPDX exceptions index (in https://spdx.org/licenses/exceptions-index.html). Many SPDX exceptions are missing.

As a result, using a valid SPDX expression with a known exception (or a project-specific one) triggers a warning such as:

warning: $.license (an SPDX license expression): warning: Unknown license exception identifier 'fmt-exception'.
Known values are listed at https://spdx.org/licenses/exceptions-index.html

This warning was triggered by a custom port with the following license field:

"license": "MIT WITH fmt-exception"

Looks like the data in https://raw.githubusercontent.com/spdx/license-list-data/8f481f509e9ed7b59b115f6a9361228f92904c5e/json/exceptions.json are not complete if compared to https://spdx.org/licenses/exceptions-index.html
