Adds test coverage for invalid empty strings (e.g. ""), non-numeric strings (e.g. "abc"), and partially-numeric strings (e.g. "12abc"), as well as valid exponential numeric strings ("1e5)
We will target enforcing non-conformant cases that should have failed to parse but didn't in upb in v30.x (our ~annual breaking release in some languages). Conformance failures to accept input we previously failed on can be landed at any time.

cmake: make DEPENDENCIES in protobuf_generate() a multi-value keyword (#19175)
It was previously a one-value keyword, so given
```cmake
protobuf_generate(
...
DEPENDENCIES
a
b
)
```
`a` would be a dependency, and `b` would be discarded (or, more precisely, added to `protobuf_generate_UNPARSED_ARGUMENTS`).
This can be confirmed with the following changes:
```diff

endforeach(proto_file)
```
Which printed "Deps: a" and "Unparsed args: b" for lite test files. With this change, it now prints "Deps: a;b" and "Unparsed args: ".
AFAIK, making `DEPENDENCIES` a multi-value keyword is mostly backwards-compatible; however, users who specified dependencies that were being ignored may be surprised to see that they are no longer ignored (which could cause build errors).
To prevent this kind of problem in the future, validating that `protobuf_generate_UNPARSED_ARGUMENTS` is empty could be useful, but to avoid potentially breaking more builds I did not do this in this PR.
Closes#19175
