libstdc++: case-sensitivity in hexfloat std::from_chars [PR105441]

The hexfloat parser for binary32/64 added in r12-6645-gcc3bf3404e4b1c
overlooked that the exponent part can also begin with an uppercase 'P'.

PR libstdc++/105441

libstdc++-v3/ChangeLog:

* src/c++17/floating_from_chars.cc (__floating_from_chars_hex):
Also accept 'P' as the start of the exponent.
* testsuite/20_util/from_chars/7.cc: Add corresponding testcase.
