Backport fixes for sharing wrappers when type attributes are involved (…

…#21537)

* [wasm] Fix the handling of i8/u8 in get_wrapper_shared_type_full (). (#19859)

Previously, these were returned verbatim, which caused sharing issues when the \ 
type had
attributes.

Fixes #19841.

* [aot] Fix the handling of r4/r8 parameter types with attributes during generic \ 
sharing. (#20217)

The attributes need to be ignored as with the other types, otherwise gsharedvt \ 
wrappers for signatures with
parameters like double f = default will not be found.

Fixes #20195.
