LibWasm: Parse struct types and support multiple types in type section
...
This patch adds support for parsing structs in the type section.
It also removes the assumption that all types in the type section are
function types, adding appropriate validation.
Spec tests struct.3 and struct.4 have been disable as this would
require expanding `ValueType` to include more heap-types.

LibWasm: Make sure try_table creates a new frame while validating
...
The spec says that while validating this opcode a new label should
be pushed.
Fixes a crash in instance.wast on WPT.

LibWasm: Properly read and validate limits for I64 memories and tables
...
Since memory64 got merged into the spec the minimum value for limits
is now actualy 64-bit and the maximum sizes for memories and tables
for I64 address types were increased.
Fixes 5 tests in memory64.wast nad 8 tests in table64.wast on WPT.

LibWasm: Avoid allocations for the label stack as much as possible
...
Namely, find an upper bound at validation time so we can allocate the
space when entering the frame.
Also drop labels at once instead of popping them off one at a time now
that we're using a Vector.

LibWasm: Hold on to the stack depth for expressions in the validator
...
This allows preallocating the value stack when pushing frames, avoiding
repeated reallocs and copies.
