build: cmake multi-pkg-config detection improvements (brotli, ldap, mbedtls)
Apply downstream patch from the vcpkg project:

- cmake/FindBrotli: streamline detecting multiple pkg-config modules.
  Add `libbrotlicommon` to `Requires.private` in `libcurl.pc`.

Apply the above idea to the rest of multi-module dependencies:

- cmake/FindMbedTLS: streamline detecting multiple pkg-config modules
  Add `mbedx509`, `mbedcrypto` to `Requires.private` in `libcurl.pc`.

- cmake/FindLDAP: streamline detecting multiple pkg-config modules

And sync these changes with autotools, and add `libbrotlicommon`,
`mbedx509`, `mbedcrypto` to `Requires.private`.
