[I] Export less when using Embedded Bundles (celix)
PengZheng opened a new issue, #675:
URL: https://github.com/apache/celix/issues/675
Currently, to support embedded bundles, we use linker flag `--export-dynamic` to make the added symbols visible to `dlopen`.
This flag will export all symbols, and thus will make `gc-sections` useless.
Considering the use case of embedded Celix into a large legacy application ([1]), which relies `gc-sections` to reduce its binary footprint, I suggest exporting less by using `--export-dynamic-symbol`.

Currently I have no usage of embedded bundles, and thus I am not against removing it.

I will remove the support for embedded bundles. In hindsight I think it is better to focus on a better bundle caching/storage system.

Do we still need embedded bundles?
I added this with the idea that you could create a executable with only embedded bundles and install and use that without needed to figure out how to install bundles and use bundles on a target platform.
But it does create additional complexity (mainly `--export-dynamic-symbol` and assembly code) and I am not sure anymore if this is worth it.
Because we are now working on a major update, it is also possible to drop embedded bundles support.
