1. An X-ray analyzer for irradiating a sample containing various components with X-rays to detect X-rays emitted from the sample, wherein an X-ray irradiation unit that irradiates the sample with X-rays includesa) an X-ray source configured to emit X-rays,b) a first multi-capillary which is composed of a large number of X-ray guiding capillaries parallel to each other, and has an incident end face arranged at a position where X-rays emitted from the X-ray source are introduced,c) a second multi-capillary which is composed of a large number of X-ray guiding capillaries, and is a parallel/point focus multi-capillary X-ray lens formed such that the capillaries are parallel on an incident end side and converged in a tapered shape mildly curved on an exit end side,d) a Fresnel zone plate, ande) a first moving section configured to move the second multi-capillary and the Fresnel zone plate such that one of the second multi-capillary and the Fresnel zone plate is selectively inserted on an X-ray optical path from the first multi-capillary to the sample. 2. The X-ray analyzer according to claim 1, further comprising a first X-ray detector configured to detect X-rays emitted from the sample in response to the X-rays irradiated to the sample through the second multi-capillary or the Fresnel zone plate. 3. The X-ray analyzer according to claim 2, wherein the X-ray irradiation unit further includes a first rotating section configured to integrally rotate the X-ray source and the first multi-capillary, a flat plate spectroscopic crystal, and a second moving section configured to move the flat plate spectroscopic crystal such that the flat plate spectroscopic crystal is located at a position where the X-ray emitted from an exit end face of the first multi-capillary reaches. 4. The X-ray analyzer according to claim 3, further comprising a second X-ray detector which is placed at a position where an X-ray diffracted from an X-ray diffraction analysis sample placed at a position where the sample is placed is able to detected, and a second rotating section configured to rotate the X-ray diffraction analysis sample and the second X-ray detector while maintaining a predetermined relationship,wherein the second multi-capillary and the Fresnel zone plate are both retracted from an optical path of an X-ray emitted from the first multi-capillary or of an X-ray emitted from the first multi-capillary and extracted from the flat plate spectroscopic crystal after hitting the flat plate spectroscopic crystal, and a diffracted X-ray corresponding to an X-ray irradiated to the X-ray diffraction analysis sample is detected by the second X-ray detector. 5. The X-ray analyzer according to claim 3, further comprising a third moving section configured to move the Fresnel zone plate on an optical axis,wherein the third moving section and the first rotating section are controlled such that a position on an optical axis of the Fresnel zone plate and an energy or wavelength of an X-ray extracted from the flat plate spectroscopic crystal are changed in conjunction with each other so as to constantly position the sample at a focal distance position of an X-ray having a predetermined energy or wavelength. 6. The X-ray analyzer according to claim 4, further comprising a third moving section configured to move the Fresnel zone plate on an optical axis,wherein the third moving section and the first rotating section are controlled such that a position on an optical axis of the Fresnel zone plate and an energy or wavelength of an X-ray extracted from the flat plate spectroscopic crystal are changed in conjunction with each other so as to constantly position the sample at a focal distance position of an X-ray having a predetermined energy or wavelength. 7. The X-ray analyzer according to claim 3, further comprising a photoelectron spectroscopic detector configured to detect photoelectrons emitted from the sample in response to irradiation of an X-ray extracted by the flat plate spectroscopic crystal. 8. The X-ray analyzer according to claim 3, wherein the X-ray source and the first multi-capillary are integrally rotated by the first rotating section, and an X-ray emitted from the sample in response to the irradiation of an X-ray extracted by the flat plate spectroscopic crystal is detected so as to acquire an absorption edge spectrum.
