x86/tdx: Fix the typo in TDX_ATTR_MIGRTABLE

The TD scoped TDCS attributes are defined by bit positions. In the guest
side of the TDX code, the 'tdx_attributes' string array holds pretty
print names for these attributes, which are generated via macros and
defines. Today these pretty print names are only used to print the
attribute names to dmesg.

Unfortunately there is a typo in the define for the migratable bit.
Change the defines TDX_ATTR_MIGRTABLE* to TDX_ATTR_MIGRATABLE*. Update
the sole user, the tdx_attributes array, to use the fixed name.

Since these defines control the string printed to dmesg, the change is
user visible. But the risk of breakage is almost zero since it is not
exposed in any interface expected to be consumed programmatically.
