[theme] Allow an arbitrary number of elevations

[millnitzluan]

Fixes #17398

• Elevation is looking for theme.shadows and logging a error message.

Doubts:

• At line 36 it's not good to start at index 0 instead 1?

• I have followed (at least) the PR section of the contributing guide.

@oliviertassinari can you have a look at this?

It looks great! I have added another commit to remove the check from createMuiTheme.

What do you mean?
