cmake: honor `CURL_DISABLE_INSTALL` and `CURL_ENABLE_EXPORT_TARGET` in lib and src

Based on existing code and commit history it appears
`CURL_DISABLE_INSTALL` means to prevent calling `install()`;
`CURL_ENABLE_EXPORT_TARGET` means to prevent calling `export()` and
`install()`s with `EXPORT` in them.

Fix them to also apply to the lib and src directories in that vain:
- lib: honor `CURL_DISABLE_INSTALL`
- src: honor `CURL_DISABLE_INSTALL`
- src: honor `CURL_ENABLE_EXPORT_TARGET`

- `CURL_DISABLE_INSTALL` follow-up to:
  aace27b0965c10394544d1dacc9c2cb2fe0de3d3 #12287
- `CURL_ENABLE_EXPORT_TARGET` follow-up to:
  8698825106f7a9987ab3924128eee885278f66bb #9638
  643ec296456ba98c536857fce3ecfd021d44d913 #7060

Closes #19144
